I was thinking the same thing,It wasnt that hard of a shot.He just took a shoulder shot.Even cassel has taken alot harder hits.Before the serie when cassel got hurt,when are d-fense was on the field.Cassel was on the phone on the sideline.then Quinn was on the sidelines throwing to copper.Then Matt goes in and gets a shoulder hit,didnt look like a hard hit at all.Think the whole things was set up.They know Kansas city fans are done with the cassel experiment.If i'm wrong,I hope cassel is o.k. and makes full recovery.Just look like it was a setup.Soon,they will probably put him on the I.R.
