Crook, who retired from East Hall several years ago, is now a music instructor at Gainesville State College.
College spokeswoman Sloan Jones says Crook is well-respected on campus and was named outstanding adjunct professor - an award voted on by students - a couple of years ago.
Jones says he has told school officials he will not be back in the classroom this year but hopes to return in January.
Crook - who also serves as associate conductor of the Northwinds Symphonic Band - was injured in a wreck on Cleveland Highway and is hospitalized at Atlanta Medical Center.
