Former WWE champion Daniel Bryan suffered a serious concussion back in April, and he’s decided to call it quits as a result.

Bryan was at “Monday Night Raw” and announced his retirement in front of a sold-out crowd at KEY Arena. He told fans he suffered three concussions in his first five months of wrestling, and they continued throughout his career.

An emotional Bryan gave a heartfelt farewell speech that ended with his signature “YES!” chant, which the crowd got into big-time. Watch how it all went down here.
