Right-hander Bobby Parnell is being shut down for the remaining 12 games of the season with inflammation of the plica in his right elbow, according to the team.

After Parnell was declared unavailable for use Sunday by Jerry Manuel, the reliever told ESPNNewYork.com he believed the issue was triceps related. An MRI was taken Monday at the Hospital for Special Surgery. The injury is expected to calm down without the need for any procedure.

"Basically just inflammation in the back of the elbow," Parnell said.

Parnell, 26, was 0-1 with a 2.83 ERA in 41 relief appearances for the Mets. He had opened the season at Triple-A Buffalo before making his season debut with the Mets on June 22. In one game at Houston this season, Parnell registered 102.5 mph with his fastball.

Last season, Parnell set a franchise rookie record with 68 appearances, which included eight starts.

Meanwhile, infielder Luis Hernandez underwent surgery Tuesday in Manhattan to repair a fractured metatarsal bone in his right foot. Dr. Jonathan Deland performed the procedure. Hernandez broke the foot fouling a pitch off Saturday, then homered and hobbled around the bases before departing.
