The fight world swiftly reacted after UFC fighter Jamahal Hill defeated Glover Teixeira in Rio de Janeiro at UFC 283 Saturday night, capturing the light heavyweight championship and cementing his place at the top of the division.

The challenger winning the wildly one-sided affair was not the only surprise that evening as the former champ also left his gloves in the Octagon, signaling his retirement from the sport.

"Glover has had a stellar career and has nothing else to prove," UFC #5 ranked middleweight Derek Brunson tweeted. "Major inspiring career! Thanks legend!"

"Thank you @gloverteixeira," former UFC middleweight champion Michael Bisping tweeted. "Legend personified."

Teixeira remained in the contest til the final bell but was unsuccessful in winning back a championship he won for the first time at UFC 267. After losing the belt at UFC 275, Texeiria was given another shot at the vacated title but was unable to overcome Hill.

After the fight, the Brazilian veteran said his toughness got him to the end but that he can no longer "keep up anymore."

"In reality though, I think I’m too tough for my own good," Teixeira explained in the middle of the Octagon. "I can’t keep up anymore. I’m gonna focus my energy on [middleweight champ] Alex Pereira. He’s gonna keep his belt for a while and go up to light heavyweight. It’s an honor to put the gloves down on the same night as Shogun."

Maurício "Shogun" Rua, also a Brazilian veteran and former light heavyweight champion, retired earlier in the night following his loss to Ihor Potieria.
