Floyd (elbow) will undergo an MRI after experiencing continued soreness during his recent throwing sessions, MLB.com reports. "We all felt like the ball's coming out pretty good, but he's still feeling some things," manager Terry Francona said. "It's a little vague, so we just think this makes sense to get it looked at. Floyd was expected to open the season as a member of the Cleveland starting rotation but those plans may be in jeopardy if the team's medical staff can't get their arms around this situation quickly.
