The Blue Jays will be without Reed Johnson for at least two months. On Monday, Toronto announced that the outfielder elected to have surgery to repair a herniated disc in his lower back -- an operation that will sideline Johnson until July, possibly longer. Dr. Thomas Tolli, a spine specialist, will perform the surgery on Johnson on Tuesday in St. Petersburg, Fla. The Blue Jays placed Johnson on the 15-day disabled list last week after the outfielder complained of pain in his lower back. An MRI exam revealed the problem stemmed from a herniated disc. It's a similar issue to one Johnson dealt with during Spring Training, when he sat out for more than two weeks.
