A battle with Non-Hodgkin lymphoma has forced Missouri head coach Gary Pinkel to retire.

Pinkel won 117 games in 15 seasons as the Tigers’ head coach and 190 in his coaching career.

Following Pinkel’s announcement, a host of former Missouri players tweeted their reactions:

Outgoing Missouri chancellor R. Bowen Loftin also tweeted his support for the longtime Tigers coach.

Associate athletic director Tim Hickman had kind words about Pinkel.

An unnamed Missouri fan tweeted this tribute to Pinkel.

A local TV reporter indicated she was stunned when she heard the news.

On Thursday, Denver Broncos linebacker Shane Ray talked about his former coach to Lindsay Jones of USA Today. Following Pinkel’s announcement, Jones shared Ray’s thoughts on Twitter.
