UFC 112: Invincible is getting closer to being a complete fight card as it looks like a pair of heavyweights will grace the octagon for the event, which is scheduled to take place on April 10 at Concert Arena at the Ferrari World theme park on Yas Island in Abu Dhabi, UAE.

Specifically, Mostapha Al Turk is close to taking on Jon Madsen and both fighters have signed bout agreements.

I think it’s safe to say that this is a make-or-break fight for Al Turk as he has lost two consecutive bouts in the Octagon, he lost his debut bout at UFC 92 to Cheick Kongo, then would lose to Mirko Filipovic at UFC 99.

Madsen is best known for his stint on The Ultimate Fighter as a member of Rashad Evans’ team. He defeated Abe Wagner, but then lost to Brendan Schaub; he would redeem himself when he defeated Justin Wren during the show’s finale.

With the addition of Al Turk and Madsen to the Abu Dhabi event, UFC 112: Invincible looks like this:

• Anderson Silva vs. Vitor Belfort
• B.J. Penn vs. Frankie Edgar
• Matt Hughes vs. Renzo Gracie
• Kendall Grove vs. Mark Munoz*
• Nick Osipczak vs. Rick Story*
• Rafael dos Anjos vs. Terry Etim*
• John Gunderson vs. Paul Taylor
• Paul Kelly vs. Matt Veach*
• Mostapha Al Turk vs. Jon Madsen*
• DaMarques Johnson vs. TBA
