When Brian Stann was forced to withdraw from his UFC on FOX 4 main event because of an injury, attention immediately turned to finding a high-profile Middleweight replacement who could give highly-touted Ultimate Fighting Championship (UFC) newcomer, Hector Lombard.

"Shango" himself even got involved, calling out Michael Bisping via Twitter even though "The Count" was booked to battle Tim Boetsh at UFC 149 next month. The promotion could have actually pulled off that switch; however, it was soon revealed that Bisping, too, was hurt.

In the video above, the former The Ultimate Fighter (TUF) winner talks about the knee injury and how it happened, as well as the uncertainty in regard to whether or not he'd be fit enough to compete against "The Barbarain" at less than 100 percent.

He clearly wasn't.

With the Bisping and Stann injuries, Lombard and Boetsch are now scheduled to tangle Scotiabank Saddledome in Calgary, Alberta, Canada, on July 21, 2012. Meanwhile, Mauricio Rua was tapped to headline the primetime mixed martial arts (MMA) event on network television opposite Brandon Vera.

Far from ideal, but not much can be done if and when professional fighters can't stay healthy.
