A key middleweight tilt in the UFC has been confirmed by Ariel Helwani on “UFC Tonight” Tuesday evening.

Mark Munoz and Chris Weidman have been signed to face off in the main event of UFC on FUEL TV 4 on July 11. A location is yet to be determined.

Munoz will be returning from surgery to clean up several bone fragments in his elbow. The surgery knocked him out of a planned No. 1 contender match with Chael Sonnen earlier this year.

Weidman has won all four of his UFC fights, including a decision victory over Demian Maia.

A planned Jon Fitch-Aaron Simpson fight is also expected for the event.
