Jacoby Ellsbury's efforts to return from a concussion have been shut down after the Yankees outfielder began experiencing headaches again.
Ellsbury suffered a concussion and sprained neck after banging his head into the center field wall while catching Alcides Escobar's fly ball on the opening pitch of a May 24 game against Kansas City. He's batting .281 with four homers and 14 RBIs.
Manager Joe Girardi says Ellsbury will rest for the remainder of the weekend and visit a neurologist when the team returns home Monday from their series in Toronto.
Ellsbury became eligible to come off the seven-day concussion list Thursday and was expected to return sometime during the weekend series. Before Ellsbury took batting practice Friday, Girardi acknowledged that timeline had become less likely.
