The main event between Randy Couture and Brock Lesnar at UFC 91 may be in jeopardy. According to 3 different sources that are either involved with the Lesnar or Couture camp, both fighters are currently battling serious injuries. Lesnar sustained a hamstring injury, that he's trying to cover up and work through, and Couture is having major shoulder problems.
This is tough news for both fighters as neither one of them seems to have much room for error going into this UFC heavyweight championship fight. Since details on the injuries are being held close to the vest, it's difficult to judge the severity of each injury and which fighter it's going to affect more. All I know is no matter how big of an opportunity it was, or how big the pay day was, I wouldn't have any interest in fighting Couture or Lesnar if I wasn't at 100%.
