Derek Brunson out of UFC 200 bout against Gegard Mousasi

Derek Brunson won't be competing against Gegard Mousasi at UFC 200. The news was first reported by Sherdog on Sunday, and was later confirmed by MMA Fighting.

Brunson, who's currently ranked No. 11 in the UFC's middleweight rankings, was forced to pull out of his bout with former Strikeforce middleweight champion Mousasi for unknown reasons. The 32-year-old middleweight is currently 6-1 in his past seven trips to the octagon. He last fought on February at UFC Fight Night 83, defeating Roan Carneiro. His fight with Mousasi was to serve as a UFC Fight Pass preliminary bout.

Although there is no current replacement opponent for Mousasi, the former Strikeforce champion called for a rematch with Uriah Hall or a fight with Vitor Belfort through his twitter account. "The Dreamcatcher" is ranked eighth in the division, and is 3-1 in his past four outings. Mousasi last fought at UFC Fight Night 84 on February where he outpointed Thales Leites.

UFC 200 takes place on July 9 at T-Mobile Arena in Las Vegas, Nevada. Daniel Cormier and Jon Jones are scheduled to headline the card in a light-heavyweight title bout.
