The Texans overcame a lot to even get to the playoffs, and now that they’re there, the obstacles keep coming.

According to Aaron Wilson of the Houston Chronicle, Texans left tackle Duane Brown is having surgery Wednesday to repair a torn quadriceps tendon suffered in yesterday’s AFC South-clinching win over the Jaguars.

He’ll be replaced in the lineup by former Broncos tackle Chris Clark, who was acquired in a trade last August, a seventh-round pick they’re glad to have spent now.

“It’s always a bummer when you lose a guy like Duane Brown, he’s the leader of our offensive line and we look to him for leadership,” Clark said. “Losing a guy like that is devastating, but we understand it’s a next man up mentality and you have to go in and perform. For me, it’s not about filling his shoes.

“It’s about allowing me to get a chance to showcase what I can do and not being the weakest link knowing these guys are counting on me to do a certain job. We have a good chemistry going.”

Clark has started four games for the Texans this year and played in 11, and they’ll need him to be strong as they open the playoffs against the Chiefs Saturday.
