HOUSTON (AP) — Case Keenum, who hasn’t played in a meaningful game since he was in college back in January 2012, will start at quarterback for the Houston Texans this Sunday in one of the tougher environments in the NFL.

Keenum will make his first appearance in a regular-season game against the rugged defense of the undefeated Kansas City Chiefs at Arrowhead Stadium, where the fans just set a Guinness record as the noisiest outdoor stadium in the world.

So be it: Keenum will start for Matt Schaub, who is out dealing with injuries to his right ankle and foot, and will try to help the Houston Texans snap a four-game losing streak.

“We’re struggling, and we’re looking for a spark,” coach Gary Kubiak said. “I think he deserves an opportunity to go out there. It’s a tough place to play. It’s a tough place to get your first start and all that good stuff. But I’m not sending him out there by himself. I’m sending him out there with his football team and the guys understand that.”

Keenum was a record-setting quarterback at the University of Houston before spending last season on the practice squad. The undrafted free agent has played in several preseason games, but hasn’t played in a game that counted since leading the Cougars to a 30-14 win over Penn State in the TicketCity Bowl on Jan. 2, 2012.

The Texans (2-4) have been hurt by penalties, turnovers and other mistakes during their skid.  Kubiak chose to go with Keenum over backup T.J. Yates, who led Houston to its first playoff win two years ago when Schaub was hurt. He struggled Sunday after Schaub was injured, throwing two interceptions, the first of which was returned for a touchdown.
