Renan Barao holds onto belt at UFC on Fuel 7

(Getty)Renan Barao held onto the UFC interim bantamweight championship belt with a fourth-round arm-triangle submission win over Michael McDonald at UFC on Fuel 7 over the weekend. At 30-1, Barao hasn't lost since 2005. He won the interim title with a win over Urijah Faber over the summer when an injury sidelined champion Dominick Cruz.

The UFC is hoping for Barao to fight Cruz this summer, as long as Cruz's leg is healed from surgeries on his knee.

In other main card fights, Cub Swanson took a decision win over Dustin Poirier, Jimi Manuwa won by TKO after Cyrille Diabbate's calf was injured, and Gunnar Nelson and James Te'Huna won decisions.
