Matt Cassel missed today's practice because of illness, the Chiefs said Wednesday afternoon.
In keeping with team policy on injuries, coach Todd Haley provided little information on Cassel's availability for Sunday's game against the Chargers in San Diego.
''This time of year, nobody feels 100 percent,'' Haley said. ''That’s why it's so important to continue to have everybody ready at all times.''
Brodie Croyle took the first-team snaps at practice. Tyler Palko, newly promoted off the practice squad, was the backup.
Haley said Palko's promotion wasn't a sign the Chiefs thought they would need him against the Chargers. The Chiefs placed cornerback Jackie Bates from their practice squad and promoted Palko.
''It’s actually a coincidence,'' Haley said. ''It really is. We had to make a move in another area and we were able to get somebody up and that determination was made . . . in (Tuesday) night’s staff meeting. That’s when we made the determination who would we thought would best serve us.
''We’ve been a little on the edge with two quarterbacks the entire year and really had a chance without there being a clear-cut guy we felt could come in and be on the game-day roster . . . The fact you can use a third emergency quarterback was the determining factor. At least it was a body we could get to the game to serve a purpose.''
Cassel made a couple of appearances at community events on Tuesday on behalf of the Chiefs.
