Patrick Saunders of the Denver Post reports that Rockies pitcher Tyler Anderson will undergo surgery on his left knee. It won’t be known until after the procedure if Anderson will be able to return at some point this season.

Anderson, 29, struggled over five starts this season, allowing 27 runs in 20 2/3 innings. He had been bothered by discomfort in his left knee since very early in the season. The Rockies demoted him to Triple-A Albuquerque earlier this month, but he hasn’t actually pitched for them due to the knee issue.

Jeff Hoffman is a candidate to take Anderson’s spot in the rotation. He has made one start in the majors this year and has otherwise pitched at Albuquerque.
