Matt Leinart’s already frustrating season has been cut short. Way short. Cardinals’ coach Whisenhunt has placed Leinart on injured-reserve following a broken collar-bone against the Rams last Sunday, effectively ending the second-year quarterback’s 2007 season. Leinart, already unhappy about sharing the two quarterback system with veteran Kurt Warner, can only watch as Warner will attempt to take control and lead the team.

Not Forgotten…Just Replaced: Matt Leinart’s replacement is quarterback Tim Rattay. The former Buccaneers and 49ers quarterback, Rattay signed with the Cardinals as a free agent for a single year.

Whisenhunt says the decision to place Leinart on IR is simply an issue of time:

“Whenever you have a fracture there will be six weeks or however long it takes to heal,” Whisenhunt said, “and then, especially because it is his throwing shoulder, you have to do the rehabilitation of it throwing the football. Who knows what it could have been? Could have been eight weeks, could have been 12 weeks…”
