Texans QB Graham Mertz believed to have a torn ACL

Texans quarterback Graham Mertz left Thursday night's game with a knee injury and it looks like it is a season-ending one for the second-year player.

Head coach DeMeco Ryans said after the game that the team feared an ACL injury and Adam Schefter of ESPN reports on Friday morning that the belief is that Mertz tore the ligament. Further testing will be done to confirm that diagnosis.
