Last I heard, the docs haven't cleared him not because of concern about contact, but rather dehydration. The coaches are proceeding as though he will not play, but they hope he will be able to at some point.
I hope for Greg's sake he has an opportunity to play. This is a fine young man and an excellent player who exemplifies all that's good in GT's student/athlete!
John Hollis, GT beat writer for the AJC, says that "Greg Gathers kidney condition may be worse than a year ago". This was said live on Hollis' interview with the BYU flagship station, KLS in Provo, Utah.
