Texans add QB Brett Rypien to deepen behind Stroud and Davis Mills after Mertz ACL injury

The Houston Texans have moved quickly to shore up their quarterback depth after Graham Mertz went down with a torn ACL in the team’s first preseason game. According to KPRC2’s Aaron Wilson as relayed by Pro Football Rumors, the Texans plan to sign veteran quarterback Brett Rypien to take the spot created by that injury.

Rypien, 30, is expected to become Houston’s third-string quarterback behind starter C.J. Stroud and backup Davis Mills. That order matters in the early weeks of the NFL season because the second and third quarterbacks often see snaps in preseason and in the first-team protection periods of practice, especially when the coaching staff wants to keep the depth stable for package-specific run and pass situations.

The timing also suggests Houston is trying to prevent a prolonged disruption to its quarterback room. With Mertz sidelined, the Texans needed another experienced arm available during the final phase of roster evaluation. Rypien’s addition provides continuity at a position where timing with the first-team or scout-team groups can influence how quickly a quarterback learns the system, reads, and cadence preferences across the week.

Rypien’s familiarity with Houston personnel is a key detail. The report notes that Rypien previously spent time with Texans offensive coordinator Nick Caley in 2023 when both were with the same organization. That background does not guarantee an immediate on-field role, but it can reduce the learning curve for terminology and offensive concepts, which are especially important for a quarterback who may be asked to handle complex playbook responsibilities even if he is not the primary backup.

For the Texans, this transaction is less about immediate competition for Stroud’s job and more about preventing a quarterback depth shortage as the season approaches. When a team loses a developmental quarterback during preseason, it can force a late scramble to find a viable option who can grasp the offense quickly enough to be credible in meeting rooms and practice reps. By adding Rypien, Houston is indicating it wants a known quantity ready to step in.

Mertz’s ACL tear also changes the internal quarterback pathway for Houston. Even without additional reporting about a timeline, an ACL injury typically removes a player from meaningful football activities for an extended period. That means Houston’s staff will have to redirect its longer-term planning for the quarterback room, leaning more heavily on the remaining depth and any late camp evaluations.

As the Texans proceed, what to watch next is how Rypien fits into the day-to-day reps during the end of camp, including whether the coaching staff uses him primarily for scripted third-quarter type work or broader scout-team and two-minute package scenarios. His performance in practice and walkthroughs, along with how the Texans structure QB1 and QB2 reps, will help determine whether he becomes a steady third-option or simply a short-term roster insurance policy.
