Yarbrough will only miss a couple of days due to his tight left groin, Rays broadcaster Neil Solondz reports.
The injury forced Yarbrough to end his appearance Thursday against the Twins early, but the move was described as precautionary and the left-hander is considered day-to-day. Manager Kevin Cash confirmed his status Friday, so it seems as though Yarbrough's preparation for the upcoming season shouldn't be significantly affected.
