Former Cleveland Cavaliers head coach, and current coach of the Greek team Olympiacos, David Blatt has been diagnosed with multiple sclerosis.

Blatt was named head coach of the Cavs in 2014 but only lasted a season and a half with the team.

He was fired halfway through the 2015-16 season despite the team’s 30-11 start to the season.
