There was a delay before the bottom of the seventh inning, and after a while, Ryan Raburn emerged from the dugout to take left field. The TBS cameras then cut to Delmon Young, who was wincing and in obvious pain. He was attended by a trainer, and he went down the steps to the dugout.
No word on what it could be, but Young did make the last out of the previous half-inning. It was a pop-up, so he wasn't exactly burning down the line. I'm not a doctor, but I do have a metric crap-ton of student loans, so I feel pretty qualified in guessing that it was a freak tweak of the ol' oblique.
It probably would have been a good idea to get Young off the field regardless, as he fields like Pete Incaviglia duct-taped to Bengie Molina, so it's probably not a big deal for this game. But Young has hit well for the Tigers in the ALDS, so they could miss him if he's hurt for the ALCS.
If the Tigers hold on, of course ...
