Brock Lesnar retired from active MMA and informed the UFC of his decision though giving no official announcement for the same.
His last fight was at UFC 200 against Mark Hunt where his unanimous decision win was later overturned to a NC after failing a pre – fight drug test and one on fight night itself and he was suspended for a year by NAC and fined $250,000.
He had retired once previously in 2011 because of a digestive condition.
