Colts face a QB they're not familiar with

INDIANAPOLIS -- The game footage on Houston Texans quarterback Case Keenum is limited for the Indianapolis Colts. Limited to one regular-season game and few preseason appearances. To get more specific, Keenum's pro career stat line is: 15 of 25 for 271 yards and a touchdown.

The Colts have to take what they can get on Keenum because they’ll be facing him on Sunday night in their third straight nationally televised game.

“Thank God we at least have one game on him with Kansas City,” Colts defensive coordinator Greg Manusky said. “We went back into the preseason, watched some of the reps that he took there, compiled those and from the players' and from the coaches' standpoint, we watched all those. It’s just trying to get a repertoire of what the guy likes and what throws he has.”

The Texans (2-5) replaced the struggling Matt Schaub with Keenum to try to salvage their season and also see if he's their quarterback of the future. Keenum set the NCAA all-time passing record (19,217 yards) while at the University of Houston.

“Yeah, it’s a little tough,” Colts cornerback Vontae Davis said. “It’s tough because you don’t have too much game film on him. You have to look at the last game he started. He’s doing pretty good.”

The Colts can’t go into the game thinking they’ll be able to easily rattle Keenum. He shook off being sacked five times to complete six passes of at least 25 yards against a Kansas City defense that's ranked in the top five in the league on Oct. 20. Colts linebacker Robert Mathis leads the league in sacks with 11.5.

The Colts have taken a hit in the secondary, as starting cornerback Greg Toler will miss Sunday’s game with a groin injury. Davis will be lined up against Keenum’s top target, receiver Andre Johnson.

“The kid has moxie,” Colts coach Chuck Pagano said. “He’s got savvy. He was cool under pressure. That’s a top-five defense that he went against. Made big plays. He’s able to extend plays. He’s got enough arm talent to beat you. Enough weapons around him. We’ve got to do a great job, number one, of stopping the run, but number two of trying to put pressure on him and get to him and make him as uncomfortable as possible.”
