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.
Durin the post-fight interview with Joe Rogan, 33-year-old Cejudo dropped another bombshell ... he's hanging up his gloves.
Cejudo essentially says he's young, he's healthy and he's got career options ... so he's going to quit while he's ahead.
