Chucky didn't look concerned, his teammates didn't look concerned, and he had no ice or heat on his groin area.
Seems to me it was something he has probably dealt with before and knows what to expect.
He may have came back in had BC made a run to tie the score, but the opposite happened when the Cards expanded the lead, so Kelsey had no reason to bring him back in.
But if he has to miss the next game, there isn't a weaker team to play than Miami. The Hurricanes are as bad as the Cards were the past two seasons.
