During Saturday's Red Sox-Blue Jays game, Boston starting pitcher John Lackey suffered an injury to his right arm. Lackey had Tommy John surgery after the 2011 season, and missed all of 2012 recovering from the surgery. Based on his arm going completely limp after he threw the pitch, it looks like he's re-aggravated the same injury.
I've put the video below the jump if you're not too keen on watching it, as it's pretty graphic.
Lackey left the game with the Red Sox trailing the Blue Jays 2-0. He had allowed two runs on five hits over 4 1/3 innings, walking one and striking out eight in the process. It's a shame that he's hurt again after he worked so hard to get back, and here's hoping he won't need another surgery, but after watching that video, it's hard to imagine that he won't.
UPDATE: Nick Cafardo is reporting that Lackey has a right biceps strain. That diagnosis is phenomenal news considering how bad it looked, but I have a feeling that it's going to end up worse after a more in-depth diagnosis.
