A heavyweight clash between Las Vegas-based Gilbert Yvel and "The Ultimate Fighter" alum Jon Madsen has been added to the UFC 121 card Oct. 23, according to sources close to the event.
Several websites initially reported Madsen would face heavyweight prospect Todd Duffee on that date, but multiple sources told the Las Vegas Sun Tuesday that bout has fallen through and Duffee will likely not compete on the card.
Bout agreements for the new matchup should be signed within the week.
Yvel (36-15-1) will be looking to rebound from back-to-back losses in his first two appearances in the UFC octagon.
The 34-year-old fighter suffered a first-round TKO loss to Junior Dos Santos in his debut with the company at UFC 108 on Jan. 2. In his most recent fight, Yvel dropped a unanimous decision to Ben Rothwell in June.
Madsen (6-0) has had no trouble adjusting to his transition to the UFC, posting three straight decision wins since his appearance on the tenth season of TUF.
The former collegiate wrestler went 1-1 while on the show, eventually falling by knockout to Brendan Schaub in the quarterfinals.
UFC 121 is scheduled to take place at the Honda Center in Anaheim, Calif., and will be headlined by a heavyweight title fight between defending champion Brock Lesnar and Cain Velasquez.
