Yan Gomes has been diagnosed with a concussion and there's no timetable for when he'll return to the Cleveland Indians.

Terry Francona said team doctors don't think at this time that Gomes will have to be placed on the seven-day concussion list.

Gomes was hit on the mask after a pitch deflected off Minnesota's Kurt Suzuki on Thursday. Gomes remained in the game, but felt ill and was removed the following inning.
