Texans Fall 27-7 to Chargers in 2026 Preseason Opener as Graham Mertz Injury Clouds Houston’s Evaluation Process

HOUSTON — The scoreboard may not have been the primary concern for the Houston Texans on Thursday night, but the events that unfolded at NRG Stadium still left the organization with plenty to evaluate.

Houston opened its 2026 preseason schedule with a 27-7 loss to the Los Angeles Chargers, in a game that was designed less as a measuring stick for the Texans’ championship aspirations and more as an opportunity for head coach DeMeco Ryans and his staff to examine the players fighting for their NFL futures.

The result was not what Houston wanted.

The bigger concern, however, came late in the first half when quarterback Graham Mertz left the game with an injury and did not return, casting uncertainty over one of the most competitive position battles on the Texans’ roster.

With franchise quarterback C.J. Stroud and several other established starters held out, Thursday night belonged to the backups, rookies and young players attempting to prove that they deserve a place on Houston’s final 53-man roster.

Some took advantage of the opportunity.

Others may have watched their cases become more complicated.

And for Mertz, what was supposed to be another important audition may have suddenly become a much more emotional chapter in his young NFL career.

Davis Mills Gives Texans an Early Spark

The Texans opened the game with veteran backup Davis Mills under center, while several regular starters—including Stroud—watched from the sideline.

Houston’s opening drive offered an encouraging glimpse of what Ryans wanted from his second-unit offense.

Mills operated behind the starting offensive line and helped move the Texans into scoring position before connecting with wide receiver Jared Wayne for a 5-yard touchdown pass in the first quarter.

For a brief moment, Houston held a 7-3 lead.

It was exactly the kind of start a quarterback competing to solidify his role wants to deliver.

Mills looked composed, moved the offense efficiently and took advantage of his opportunity to work with Houston’s first offensive line.

He eventually finished the night 9-of-15 passing for 82 yards and one touchdown.

The stat line wasn’t spectacular, but preseason football is often about more than production.

Mills’ experience and familiarity with the Texans’ system remain important assets, particularly in a quarterback room led by Stroud.

But Thursday’s game was also supposed to provide a significant opportunity for the player behind him.

That was where Graham Mertz entered the story.

Graham Mertz Gets His Chance—Then Everything Changes

After Mills completed his work, Graham Mertz took over.

For the young quarterback, the preseason opener represented far more than another exhibition game.

Mertz entered training camp competing for the QB3 position behind Stroud and Mills, trying to establish himself as a dependable long-term option inside the Texans’ quarterback room.

Every snap mattered.

Every decision mattered.

Every preseason series represented another opportunity to convince Houston’s coaching staff that he belonged.

Mertz had spent much of his 2025 rookie season dealing with injury issues after arriving in Houston as a sixth-round selection from Florida.

The 2026 preseason was supposed to offer him a chance to rebuild momentum.

Instead, the night took a painful turn.

Late in the second quarter, Mertz left the game after suffering an injury and did not return.

At the time, there was no immediate official update regarding the nature or severity of the injury.

The uncertainty immediately became one of the most significant storylines of the game.

For Mertz, the timing could hardly have been worse.

A young quarterback fighting for a roster spot cannot afford to lose valuable evaluation time. The preseason schedule is limited, and every missed practice or game can create additional opportunities for another player to step forward.

The Texans now face a difficult waiting period as they determine exactly what Mertz’s injury means moving forward.

And depending on the eventual diagnosis, Houston’s quarterback depth chart could suddenly become a much bigger discussion.

Chargers Take Control After Houston’s Fast Start

After falling behind early, the Chargers gradually took control of the game.

Los Angeles running back Amar Johnson emerged as one of the night’s most productive players, repeatedly creating problems for Houston’s defense.

Johnson scored on a 7-yard rushing touchdown in the second quarter before later adding another score on a 1-yard run in the fourth.

His impact extended beyond the two touchdowns.

Johnson also produced a 55-yard reception, helping create momentum for the Chargers and demonstrating why preseason games can be so important for players attempting to earn attention.

The Chargers continued to capitalize on opportunities as Houston struggled to maintain offensive rhythm.

Los Angeles added field goals before quarterback D.J. Uiagalelei delivered a late touchdown pass to help secure the 27-7 final score.

For the Texans, the second half became increasingly difficult.

The offense struggled to sustain drives, putting additional pressure on the defense.

Houston’s defensive units spent extended stretches on the field, and the Chargers’ depth players took advantage.

By the final whistle, the Texans had scored just seven points—the touchdown produced during their opening offensive sequence.

It was an uneven performance, but Ryans is unlikely to view the night through the same lens as fans focused solely on the final score.

For DeMeco Ryans, the Real Test Isn’t the Scoreboard

Ryans has consistently emphasized the purpose of preseason football.

These games are about evaluation.

They are about identifying players who can contribute when the regular season begins.

They are about determining which young players deserve additional opportunities—and which roster battles remain unresolved.

That process was on full display Thursday night.

Stroud did not need preseason statistics to prove his importance to the franchise.

The same was true for several established Texans players.

The spotlight instead shifted toward the athletes whose NFL futures remain uncertain.

Who can provide depth?

Who can contribute on special teams?

Who has shown enough to survive final roster cuts?

And perhaps most importantly, which players can be trusted when injuries inevitably test the depth of the roster?

The answers to those questions won’t be determined by one preseason game.

But Thursday night provided valuable information.

The offensive inconsistency revealed areas that need improvement. The defense will review missed opportunities and examine how Los Angeles created explosive plays.

The quarterback situation, meanwhile, now carries an additional layer of uncertainty because of Mertz’s injury.

The Mertz Situation Could Change the QB3 Competition

Before Thursday night, Mertz had entered camp as the primary candidate for the third quarterback role.

His development was one of the quieter storylines surrounding the Texans’ roster.

Now, it could become one of the most important.

Mills remains an experienced option behind Stroud, but NFL teams understand how quickly quarterback depth can become a crisis.

Houston will need to determine Mertz’s availability before making any major decisions, but the injury could potentially affect how the organization approaches the remainder of the preseason.

If Mertz misses significant time, another quarterback could receive additional practice and game opportunities.

If the injury proves minor, the focus could quickly return to his development and competition for a roster spot.

Until the Texans provide further information, however, the situation remains unresolved.

And that uncertainty may be more significant than anything represented by the 27-7 score.

Texans Turn Attention to the Raiders

Houston won’t have much time to dwell on its preseason-opening loss.

The Texans are scheduled to return to action against the Las Vegas Raiders on Thursday, August 20, at 8:00 p.m. ET at NRG Stadium.

The nationally televised game on ESPN will provide another opportunity for Ryans and his staff to evaluate the roster as final cuts continue approaching.

Expect the Texans to continue experimenting with personnel.

Expect young players to receive meaningful snaps.

And depending on the availability of Mertz, expect Houston’s quarterback depth chart to remain under close observation.

The regular season opener against the Buffalo Bills on September 13 is the destination.

Everything between now and then is preparation.

The Texans didn’t leave Thursday night with the result they wanted.

But in preseason football, wins and losses rarely tell the entire story.

The real value comes from what a team learns when the lights are on.

For Houston, the opening game provided several answers—but it may have created one question that now matters more than all the others:

How long will Graham Mertz be out, and could his unexpected setback change the entire race for the Texans’ final quarterback spot?
