Rays manager Kevin Cash said Sunday that pitcher Drew Smyly has been slowed by shoulder tendinitis, not his offseason finger injury, the Tampa Tribune reports.

Cash added that "it's fair to say there is concern" when asked if Smyly would be ready for the start of the regular season. It was reported Saturday that Smyly was tentatively expected to throw a simulated game Monday and make his spring debut Saturday. If that timetable changes, the team may have to plan to be without the pitcher in the initial rotation.

Smyly said Sunday that the issue is nothing serious and that he'll resume throwing after a few days of rest.
