Johnson was originally scheduled to have the surgery last week but in the days prior to it, he accidentally cut his injured leg while moving a motorcycle he was in the process of selling. His surgeon informed him that surgery would not be possible until the cut was healed up, forcing the postponement.
His agent Ken Pavia told MMA Fighting that the surgery was likely to be performed next week, and that the rehabilitation phase should only require a few weeks.
Johnson originally injured his left leg over a year ago before re-aggravating it recently. The injury was so bad that at one point Johnson had trouble putting weight on it.
The 26-year-old Johnson (8-3) is coming off a loss to Josh Koscheck in a result that snapped a three-fight win streak. Johnson is still hoping to match up with the surging John Howard, who has won all four of his fights in the octagon and is 14-4 overall. The pair has had a long-running feud and had been scheduled to fight at the recent UFC on Versus event until Johnson's knee caused him to withdraw from the bout.
