Texans fear Graham Mertz tore ACL in preseason game

At NRG Stadium in Houston, the Texans may have lost a key depth piece before the regular season even starts. Backup quarterback Graham Mertz is feared to have torn his ACL after getting hurt in preseason action, a setback that could force Houston to revisit its plans behind starter C.J. Stroud.

Mertz joined the Texans as a developmental quarterback option, and his preseason reps mattered. Houston has spent training camp sorting out depth across the roster, and quarterback is one spot where injuries can change the conversation fast. A serious knee injury this early in August would leave the Texans thinner at a position no team wants to scramble to fix.

Graham Mertz injury clouds the Texans backup plan

The concern, according to reports, is that Mertz suffered a torn ACL. The Texans had not publicly confirmed the full diagnosis at the time of the report, but the fear alone points to a long absence if testing matches that early outlook. An ACL tear typically ends a player’s season and shifts a team’s short-term roster math right away.

Houston entered camp with Stroud locked in as the starter, while the competition behind him remained important for preseason snaps, emergency depth, and practice work. Mertz was part of that group, trying to earn trust and carve out a role on the roster or practice squad. Losing him would cut into the team’s flexibility as coaches work through final preseason evaluations.

Houston may need another quarterback before roster cuts

The timing matters as much as the injury. August is when teams decide who can handle live game work, who stays for developmental upside, and who gets released as roster limits tighten. If Mertz is out for the year, the Texans could need another arm for camp and preseason prep, even if Stroud’s role does not change.

Houston’s front office now faces a practical question. Does the team promote another quarterback option internally for extra reps, or bring in a veteran or camp arm to help close out the preseason? That decision could come soon, because preseason practice and game planning do not slow down while medical evaluations come in.

The Texans still have time to adjust before Week 1, but losing Graham Mertz would be a real blow to depth at NRG Stadium. Houston’s next update should bring clarity on the diagnosis and on whether the club adds another quarterback before the next round of preseason work.
