“Brady said he is ready to go, and I’m sure he’s excited about the possibility, but at this point he’s not officially cleared, so I can’t make a determination until I can find out exactly what the prognosis is for him,” Crennel said. “That’s what I’ll do. I’ll find out and we’ll go from there.”

I don't think he is referring to the doctors clearing Quinn. Pioli hasn't officially cleared Quinn to play. Quinn will probably be inactive next week and end up on IR at some point.
