The UFC injury bug continues to spread, but at least one fighter got the chance to enter the cage before being struck by it. UFC heavyweight Travis Browne Tweeted Monday he'll be out of action from two to four months after suffering a hamstring injury in his first-round TKO loss to Antonio Silva at UFC on FX 5 last Friday.

As Browne indicates in the Tweet, he will not require surgery to address this particular injury.

Browne sustained his injury early in the first round of his bout with 'Bigfoot' Silva. While it isn't clear which specific action lead to it, Browne appeared to be unable to stand on his left leg midway through the first round. The Greg Jackson-trained heavyweight wobbled as he tried to put weight on it and stumbled around the Octagon trying different offensive techniques such as switching stances or various kicks.

Silva eventually backed Browne against the fence where he landed a blistering right hand that sent 'Hapa' crashing to the mat. A few more unanswered punches from the Brazilian forced referee Herb Dean to call a halt to the action. The end came officially at 3:27 of the very first frame.

The loss is Browne's first professional defeat and brings his UFC record to 4-1-1. He holds an overall MMA record of 13-1-1.
