Trey Yesavage left Tuesday’s start against the Astros with a trainer.

Yesavage appeared to injure his left knee on a warmup pitch prior to the third inning and was immediately lifted from the contest. The 23-year-old departed after firing a pair of scoreless frames. It would be a colossal loss for the Blue Jays, and fantasy managers as well, if he were to miss any time over the final two months. There should be an update on his status shortly.
