Was listening to the "Opening Drive" this morning, and Cecil Hurt said it's very likely that Black will play on Saturday. As far as the redshirt worries, he made a great point that "the only real impact it will have is in 2016. If he can contribute to win a National Championship, you have to do it (play him)."

Also, Tom Luginbill joined "The Roundtable" yesterday and he gave a fantastic overview of Black, going so far as to say he was "the most explosive wide receiver in the 2012 class." You can hear that interview here (skip to about the 7:20 mark):
