How long do you expect Matt Cassel to be out of action for KC Chiefs and that also for his team (KC Chiefs) as?

well. Cassel whom who is currently recovering a emergency laparoscopic appendectomy (wed., 12/8). By the way he didn't make the trip out SD since hes was declared out of the game and etc. In his replace will backup QB (Brodie Croyle). At the same time do you expect The Chiefs do keep their strategy about him or any other player for that matter on the team as they did this past week or what?
