Dodgers pitcher Brett Anderson will undergo arthroscopic surgery to repair a bulging disk in his lower back on Thursday, a procedure that Manager Dave Roberts said would sideline the oft-injured left-hander for three to five months.
Anderson, who had a similar procedure in 2014, had approached the spring confident that a rigorous winter regimen to strengthen his midsection would eliminate the lower-back problems that have plagued him for several years.
But Anderson felt discomfort in his lower back after a live-batting practice session earlier this week and on Wednesday underwent an MRI test, which revealed the bulging disk.
