MINNEAPOLIS — The back injury that put Alfredo Aceves on the disabled list could be season-ending and might result in surgery to repair a bulging disc.

Aceves stopped a throwing session Tuesday in Tampa, Fla., and is in New York to be examined by Dr. Chris Ahmad.

According to Joe Girardi, nobody knows when or if Aceves will try to throw again.

“He has a disc problem,’’ Girardi said of the valuable right-hander who hasn’t pitched since May 8 in Boston when he felt something in his back covering first base. “It’s something a lot of players deal with it when it’s not symptomatic and it’s symptomatic.’’

Aceves, who is 3-0 with a 3.00 ERA in 10 games, is valuable because he can fill multiple roles.
