Gary Pinkel is resigning from his post as Missouri Tigers head coach due to health reasons.
Pinkel was diagnosed in May 2015 with non-Hodgkin lymphoma, the school said on its website.
He will coach the rest of the season through Dec. 31 unless a new coach is found.
"I made the decision in May, after visiting with my family, that I wanted to keep coaching, as long as I felt good and had the energy I needed," Pinkel said in the statement. "I felt great going into the season, but also knew that I would need to re-assess things at some point, and I set our bye week as the time when I would take stock of the future.
