UFC 160 Update: Stephen ‘Wonderboy’ Thompson, Amir Sadollah Set for Welterweight Clash

UFC officials announced the booking Wednesday, one day after revealing that heavyweight champ Cain Velasquez will defend his title against Antonio Silva in the UFC 160 main event. The May 25 show airs live on pay-per-view from MGM Grand Garden Arena in Las Vegas and will also see former champion Junior dos Santos lock horns with Alistair Overeem.

Thompson, 30, was dealt his first defeat as a mixed martial artist in his last outing, falling by unanimous decision to veteran Matt Brown last April. The decorated kickboxer was slated to return to the Octagon in November before a knee injury forced him to withdraw from his UFC 154 booking against Besam Yousef. Thompson made his UFC debut roughly one year ago at UFC 143, knocking out an overmatched Daniel Stittgen with a first-round head kick.

The winner of “The Ultimate Fighter” Season 7, Sadollah, 32, has competed exclusively in the Octagon during his four-year career, posting six wins against four defeats. Sadollah fought twice last year, opening 2012 with a split decision victory over Jorge Lopez before falling on points to former title challenger Dan Hardy at September’s UFC on Fuel TV 5.
