Tolleson has been dealing with back spasms in recent days, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

Tolleson hasn't pitched since making his Grapefruit League debut March 3, and it appears that the injury was the reason why. The Rays don't seem to be fearing that the back issues will put Tolleson at risk of missing Opening Day, so the right-hander should still remain in the hunt for a middle-relief role to begin 2017.
