Dennis Fithian is saying on 97.1 that he hears from his sources that Rashan Gary is expected to play tomorrow, likely in limited minutes. He's not the kind of guy who rushes to the air with information unless his sources are good, so I'd put confidence in this as pretty high.
He kept referring to it as a "Willis Reed situation," without explaining what that meant. I'm assuming he's referring to Reed playing in the 1970 NBA Finals with a thigh injury, when he wasn't expected to play.
Fithian also said his sources say Tarik Black won't play tomorrow, but probably will against Penn State. Take it all for what it's worth.
