With all the quarterback injuries in the past week, I'm not surprised former Kansas City Chiefs QB and current free agent Brodie Croyle is getting a workout. The Houston Texans worked out four quarterbacks, including Croyle, this week.

The Texans, of course, are working without QB Matt Schaub, who suffered what's believed to be a season-ending foot injury.

But Houston's not the only team dealing with quarterback troubles.

The Chiefs, obviously, are without QB Matt Cassel. The Chicago Bears lost QB Jay Cutler for most of the regular season in Sunday's victory over the San Diego Chargers (who have a quarterback playing like he's hurt). QB Michael Vick missed the Philadelphia Eagles Sunday night win over the New York Giants. The Arizona Cardinals have been playing without QB Kevin Kolb. QB Ben Roethlisberger has a finger injury (but won't keep him out).

That's a lot of injuries, even a few playoff-contending teams.

For Croyle, this is his third known tryout with a team since the Chiefs didn't re-sign him. He had a short stint with the Arizona Cardinals and reportedly worked out for the Indianapolis Colts and Miami Dolphins.
