Former UFC middleweight title challenger Paulo Costa underwent surgery on his hand after his fight against Luke Rockhold at UFC 278.

The Brazilian won by unanimous decision, but suffered a serious hand injury during the fight - he broke one of his metacarpal bones.

In his last interview, 31-year-old Costa said he planned to fight in two months, but now he expects to return on January 21 at UFC 283 in Rio de Janeiro.
