Yarbrough was removed from Thursday's game against the Blue Jays with an apparent injury, Marc Topkin of the Tampa Bay Times reports.
The left-hander followed opener JT Chargois and allowed a pair of solo homers during the second inning, and he was lifted after initially taking the mound for the third frame. The 30-year-old should be considered day-to-day until more information is available on the injury.
