Ultimate Fighting Championship (UFC) may have been unable to book Chael Sonnen vs. Mauricio Rua for UFC 161, however, the match up has come to fruition and it will serve as the main event of the UFC on FOX Sports 1 debut event in Boston, Mass., on Aug. 17, 2013.
Sonnen himself announced the five-round light heavyweight match up on Tuesday's (June 4, 2013) edition of FUEL TV's "UFC Tonight."
The possibility of a Sonnen-Rua bout first came to light when Antonio Rogerio Nogueira pulled out of his UFC 161 match up with "Shogun" due to a back injury and the former 205-pound champion was left without an opponent.
In typical fashion, Sonnen jumped into the hero role and sent a message to the Brazilian on Twitter stating he was "available" to step in to fight on just 13 days notice.
Talk among fans and media outlets about Sonnen replacing Nogueira spread like wildfire in the following hours a report surfaced out of Brazil that Rua's camp had agreed to the match up and the fight would indeed fill the role as the new UFC 161 co-main event.
That was the last of the news until another report came out of Brazil saying the fight had fell apart because of the fact Sonnen was unable to get a Canadian visa in time for the event.
Rua was then pulled from the card in Winnipeg with the promise that he would fight "soon," with the 31-year-old later hinting that he would compete at the UFC on FOX Sports 1 debut event in Boston. He was exactly right, and Sonnen will be his opponent in what will be the first-ever main event UFC fight on FOX Sports 1.
