The UFC seem to be dealing with a an unusual number of injured fighters recently, which has left them with a few headaches as they try to find competitive replacements that won’t weaken their upcoming cards.

After recent call-offs such as Mark Coleman pulling out of his fight with Tito Ortiz and Brock Lesnar calling off his title bout with Shane Carwin, the last thing the organization needed was more injury problems.

Unfortunately for them, two fighters, namely Thiago Alves and Kurt Pellegrino have now been added to their rapidly expanding casualty list.

Thiago Alves had only recently been announced as Jon Fitch’s next opponent last week, (after Fitch’s original opponent Ricardo Almeida was also forced to cancel due to an injured knee) but today it has emerged that Alves has suffered a torn posterior cruciate ligament which will not heal in time for him to fight at UFC 107.

Meanwhile, Kurt Pellegrino has withdrawn from his next fight against Frankie Edgar at The Ultimate Fighter 10 Finale due to a back problem.

We’ll keep you updated when we find out on who there replacements are going to be.
