The Yankees received a scare on Sunday afternoon with some friendly fire.

Carlos Rodon, throwing his second live batting practice session of the week to continue his rehab process, hit Willie Calhoun on the left arm with a fastball at Yankee Stadium.

Calhoun looked to be in considerable pain and walked off the field with a trainer.

However, Calhoun said he’s good to go for Sunday night’s game against the Red Sox, in which he’s set to bat leadoff and start in right field.

Calhoun said a nerve in his elbow/bicep area got hit and it went numb for a few minutes.

Rodon was clearly concerned for his teammate, walking in from the mound to check on Calhoun before continuing his session with a strikeout of Harrison Bader.

Calhoun has given the Yankees a boost lately, including a go-ahead solo home run on Saturday night.

He had battled through injuries earlier in his career but had stayed healthy through the first two months of this season.

Rodon, meanwhile, had a conversation with manager Aaron Boone after the first inning of his live session but then went back out for a second inning.
