Former Georgia and Miami head coach Mark Richt has been diagnosed with Parkinson’s disease. He revealed his diagnosis publicly with a message on Twitter on Thursday night.

Richt retired from coaching following the 2018 season.

“I have been waddling around lately and people have asked what’s wrong. I’ve decided to tell everyone at the same time. I have been diagnosed with Parkinson’s,” Richt said. “Truthfully I look at it as a momentary light affliction compared to the future glory in heaven. Thank you Jesus for promising us a future blessing of glorified body that has no sin and no disease. In the meantime I am going to enoy the blessings that I do have. See you on the ACC Network!”

Richt was the head coach at Georgia from 2001-15. He amassed a 145-51 record in 15 seasons and posted an 83-37 record in SEC competition. The Bulldogs won five SEC East titles and two conference championships under Richt’s leadership.

From 2016-18, Richt coached at Miami, his alma mater. The Hurricanes were 26-13 in those three seasons, including a 10-3 year in 2017.

Since stepping away at Miami, Richt has been a college football analyst for ACC Network.
