Boston Red Sox manager Alex Cora provided a concerning update on slugger Rafael Devers, who's dealing with a shoulder injury.

Amid an ostensibly unresolved positional battle, Rafael Devers' health (or lack thereof) further complicates matters for the Boston Red Sox. He's bluntly declared himself a third baseman. Yet, manager Alex Cora has left the door wide open for prized free-agent acquisition Alex Bregman to man the hot corner.

Rafael Devers was scheduled to see his first spring training action either Tuesday or Wednesday, but shoulder injuries will keep him sidelined until Saturday.
