The UFC's highly anticipated White House card and Khamzat Chimaev's first title defense highlight what's happening in April, May and June.

It’s a battle of teammates as the UFC returns to the Meta APEX this weekend.

The Ultimate Fighting Championship kicks off its busy April with a Meta Apex card, which is now official following the UFC Vegas 115 weigh-ins and two weight misses. Headlining the 13-fight card is a fight between lightweight veteran Renato Carneiro and prospect Chris Duncan.

UFC is headed back to Las Vegas. This week, Chris Duncan aims to break into the lightweight top 10. Renato Moicano, Duncan's opponent, is no stranger to comebacks as he prepares to quell Duncan's rise. The two clash at UFC Fight Night on Saturday.

Over the last few years, Arman Tsarukyan has become something of a bad boy in the eyes of UFC fans. He punched a fan during the ring walk for his UFC 300 fight with Charles Oliveira, and allegedly broke Dan Hooker’s nose during their final face-off before UFC Qatar.
