i didn't see madsen's injury but i did see cassell's.. not so sure what happened, though.. it wasn't from a foul or something, from what i saw..
cassell was just dribbling it, and then he suddenly just had to let the ball go and pass it to someone and he immediately went to the announcer's table and lay on the floor near it.. he couldn't get up, and he had to be helped to walk (or limp) off the court..
i'm GUESSING it's his hip, which he had surgery on in the offseason, cause i really didn't see any contact for that to happen.. so i'm thinking it could be an old injury.. i heard the commentators's say he may have had a leg injury.. but there was no official report on it yet..
