NEW YORK (WFAN) – The Mets may be without starter Dillon Gee for the remainder of their surprising season.

Gee will have surgery Friday in St. Louis “to repair a damaged artery” in his right shoulder, according to the New York Daily News.

The 26-year-old was placed on the 15-day disabled list this week after a blood clot was found in the shoulder. Gee complained of numbness in the fingers of his pitching hand Sunday. Tests on Monday revealed the clot, which was broken up with a catheter.

The Mets said in a statement Wednesday that Gee was ready to be discharged from New York Presbyterian Hospital and would explore his options, including surgery. He was slated to start the team’s first game after the All-Star break Friday night against Atlanta.

Clots could resurface because “half of the artery in question was damaged,” the Daily News reported, making blood thinners not the best option.

“It’s probably not likely he returns this year, but it’s possible,” a source told the paper. “It’ll insure Dillon’s long-term health. He’ll have a full recovery and no issues going into (spring training).”

Gee is 6-7 with a 4.10 ERA over 17 starts this season. Miguel Batista will likely take his spot in the rotation in the short-term.
