David Wright’s season and possibly career may hang in the balance of a medical decision that should be made by the end of the week.

Wright, who is in Los Angeles to confer with back specialist Dr. Robert Watkins, may need surgery to repair a herniated disc in his neck, Mets general manager Sandy Alderson said yesterday.

Alderson would not speculate if surgery would end Wright’s season, but the Mets captain already was having a difficult time playing through his spinal stenosis before he went on the disabled list on June 3.

“David is still in Los Angeles and I would expect we would have some resolution of his situation in the next two or three days,” Alderson said. “By that I mean exactly what the next step is, whether that is rehab, as originally contemplated, or something else.”

Wright, 33, is signed through 2020. He played in 37 games before going on the disabled list. The Mets have been using Wilmer Flores at third and reacquired Kelly Johnson from the Braves. If Wright needs surgery, Alderson may try to trade for a full-time replacement. “David’s situation is a little bit fluid right now,” Alderson said.

One long shot candidate who has drawn the Mets’ interest: Cuban infielder Yulieski Gurriel, who is a free agent at the age of 32. Gurriel is expected to be nearly major league-ready for whichever team signs him.

“We’re taking a look at that situation,” Alderson said.

The Mets hosted the Pirates last night without five injured regulars: Wright, Lucas Duda, Travis d’Arnaud, Michael Conforto and Neil Walker. Juan Lagares was scratched from the lineup after undergoing a dental procedure.

Conforto had a cortisone shot in his left wrist on Monday to help deal with discomfort from strained cartilage. He hopes to return in a few days.

Walker did not play because of a sore back. He also was examined by team doctors on Monday.

D’Arnaud is on schedule to return next Tuesday from his right rotator cuff strain. He is playing for Single-A St. Lucie and will finish his rehab assignment with Triple-A Las Vegas, Alderson said.

Duda is in Port St. Lucie, Florida, resting the stress fracture in his lower back.

Also, Zack Wheeler will throw a simulated inning with the Mets’ Gulf Coast League team early next week. The Mets are hopeful Wheeler will return from Tommy John surgery after the All-Star break.
