UFC middleweight Nick Catone has been forced to withdraw from his second straight event after succumbing to an injured shoulder while preparing for his UFC Fight Night 22 bout on Sept. 15 in Austin, Texas.

MMA DieHards reports that Catone's team mate, Dave Branch, will step in to replace him against opponent Tomasz Drwal.

Branch made his UFC debut against Gerald Harris last month at UFC 116, falling to the "Hurricane" after being slammed into unconsciousness midway through the third round.

It was the first career loss for the Brooklyn native who scored consecutive submission wins (rear naked choke) over Dennis Olson and Derrick Mehmen under the Bellator banner prior to his Zuffa debut.. None of his six wins have gone the distance and he's a well balanced finisher at three subs and three (T)KO's.

Like Branch, Drwal would probably like to forget his last appearance inside the Octagon. After stringing together three straight wins, the "Gorilla" was forced to surrender his heel to muscular submission master Rousimar Palhares at UFC 111 back in March.

He'll need to once again keep his submission defense in check against the crafty Branch when they collide next month.

UFC Fight Night 22 will feature a "Great" main event between perennial middleweight contender Nate Marquardt and up-and-coming grappling stud Rousimar "Toquinho" Palhares.

TUF alumni and lightweight standouts Matt Wiman and Mac Danzig will also hook 'em up in a rematch from their UFC 115 bout that ended in controversy back on June 12.
