ST. PETERSBURG, Fla. — Yankees right-fielder Xavier Nady will be put on the disabled list with a right elbow injury and could be sidelined for an extended period.

Joe Girardi said Wednesday that the initial report from an MRI exam on Nady’s elbow “is not good.”

“We’re planning on DL’ing him Thursday,” Girardi said.

Nick Swisher will replace Nady in right field.

Nady felt a sharp pain while making a throw in the seventh inning of Tuesday night’s 7-2 win over Tampa Bay. He had elbow ligament replacement surgery on Sept. 29, 2001.

“It’s sore,” Nady said. “I’ll get a better understanding (Thursday). The original report didn’t look great. It’s frustrating. It’s tough.”

Nady will be re-examined by Yankees team doctor Christopher Ahmad on Thursday. Neither Girardi nor Nady would disclose details about the initial medical report.

“Let’s hope Dr. Ahmad can put a brighter picture on it,” Girardi said.
