Deion Sanders will not make his long-awaited Pac-12 media day debut on Friday.

The Colorado Buffaloes’ first-year head coach is scheduled to have a «routine follow-up» medical procedure related to blood clots in his legs on Thursday, the university announced.

Sanders will recuperate during the conference’s media day, with defensive coordinator Charles Kelly taking Sanders’ place at the event.

«Following the success of his latest procedure and on the advice of his physicians, Coach Prime is scheduled for a subsequent routine follow-up procedure on July 20,» a university spokesperson said in a statement.

In a video posted to YouTube on Wednesday, Sanders announced that blood clots in his right leg would be treated in this latest procedure. Surgery last month removed the clots in his left leg. He said Thursday’s procedure would also straighten the remaining toes on his left foot.

«I want you to hear it from the horse. I don’t like rumors and he says and she says. And they said, okay, that’s what I said. Is that okay? I apologize for not being at the Pac-12 media day to have another surgery tomorrow,» Sanders said in the video.

“They already took care of themselves and got them off this leg,” Sanders said later in the video. «Now, we have to get them out of there.»

Sanders previously mentioned that a procedure on his right leg would happen «soon.» The NFL legend also noted that surgery would have to be performed to remove the blood clots before doctors could straighten his toes.

During the 2021 Tigers football season, Sanders would often use crutches or ride a scooter on the sidelines.
