Long-time Vanderbilt play-by-play broadcaster Joe Fisher is resigning from his position and entering a rehab facility. This comes shortly after Fisher was reportedly slurring his words during Monday night’s coaches show on ESPN 102.5 The Game.

Fisher revealed the news via his Twitter account:

During the broadcast, Fisher repeated different versions of the same questions to interim coach Todd Fitch, according to The Tennessean. This was the first coaches show since the firing of Derek Mason. Willy Daunic announced on 102.5 The Game that he’s replacing Fisher for Vanderbilt’s final 2 games.

In addition to football, Fisher also served as the play-by-play announcer for Vanderbilt basketball.

Vanderbilt athletics director Candice Lee issued a statement via Twitter regarding Fisher’s resignation.

“We appreciate your service and will never forget the great moments and memories shared with Commodore Nation,” Lee said “We now applaud your courage. Focus on what matters most & take great care of yourself on this journey. We wish you all the best.”
