HOUSTON — With Deshaun Watson’s year done, the Houston Texans will look to Tom Savage to try and salvage their season.

Coach Bill O’Brien confirmed that Watson was out for the season on Friday, a day after the star rookie quarterback tore the anterior cruciate ligament in one of his knees during practice. O’Brien said he didn’t have any other details on the injury, and wouldn’t say if Watson will have surgery.

A fiery O’Brien brushed aside the notion that Watson’s injury signaled doom for this team.

“We’re not going to give in to what’s out there — (that) the demise of the Houston Texans is upon us,” he said. “Like that’s ridiculous. We’re going to show up and fight and play.”

Savage started the season opener, but he was benched at halftime in favor of Watson, who started each game since. Savage will make his fourth career start when the Texans host the Colts on Sunday.

“You can’t really replace Deshaun Watson. You know what I mean,” Savage said. “The kid’s been playing absolutely lights out. But that’s not my job. My job is to go out there and help this team win and do whatever I can to help.”

Watson was in the locker room before practice on Friday, but a team official said he didn’t want to speak to reporters.
