[KC Chiefs.com] Chiefs quarterback Matt Cassel missed today’s practice because of an appendectomy, the Chiefs said today.

If that’s the case, the Chiefs are looking at a best-case scenario of losing Cassel for at least two weeks, this Sunday’s game at San Diego and the following week at St. Louis.

The Chiefs announced Cassel’s procedure was successful and said they expect Cassel to return to work this week.

Brodie Croyle took the first-team snaps at practice. Tyler Palko, newly promoted off the practice squad, was the backup.
