Phil Baroni will return to the Octagon following a four-and-a-half-year absence at UFC 106 “Lesnar vs. Carwin” on Nov. 21 in Las Vegas, the promotion announced Wednesday.

“The New York Bad Ass,” who had his start as a middleweight at UFC 30 in February 2001, will face “The Ultimate Fighter 7” winner Amir Sadollah in a welterweight contest.

Baroni lost a unanimous decision to Joe Riggs at Strikeforce “Lawler vs. Shields” on June 6 in St. Louis before jumping promotions. Sadollah will look to move past a 29-second defeat against Johny Hendricks at UFC 101 last August in Philadelphia.

In another welterweight bout, Marcus Davis will meet American Top Team’s Ben Saunders. A native of Maine, Davis returns to U.S. soil following a split decision loss to Brit Dan Hardy at UFC 99 in Cologne, Germany, last June. Saunders suffered a second-round stoppage at the hands of Mike Swick on the same card.

Lightweights George Sotiropoulos and Jason Dent will also meet on the event’s undercard. Both “Ultimate Fighter” graduates, Sotiropoulos and Dent currently sport four-fight win streaks as well.

UFC heavyweight champion Brock Lesnar will make his second title defense against fellow NCAA champion Shane Carwin in the main event, and Tito Ortiz tackles Mark Coleman in the first fight of his new multi-fight contract with the UFC.
