Matt Cassel is likely out for 2-4 weeks due to MCL and ankle injuries putting the start of the season in jeopardy.  Cassel has completed 11 of 19 passes for 114 yards with 1 TD pass (92.9 QB Rating) this pre-season.  He has been without a doubt the best QB on the Chiefs’ roster.  If he can’t go when the season opens, Tyler Thigpen will get the call.  He has completed 15 of 29 passes (51.7%) for 96 yards with 1 TD pass and 1 interception (56.1 QB Rating).  He has also carried the football 6 times for 41 yards (6.8 ypc) in the pre-season.  Thigpen proved last season that he is a capable starting QB so the Chiefs are fortunate that they didn’t trade him before the season started.
