Shocker from Henry Cejudo -- the UFC superstar just unexpectedly retired from MMA after knocking out Dominick Cruz at UFC 249.
Cejudo -- aka Triple C -- fought like a champion against Cruz, ending the fight in the 2nd round with a devastating knee to the head, followed by roughly 11 unanswered punches. The ref finally stepped in and called it.
During the post-fight interview with Joe Rogan, 33-year-old Cejudo dropped another bombshell ... he's hanging up his gloves.
