The Mets’ agreement with their first-round draft pick Kumar Rocker is in limbo after the team expressed concerns with the right-hander’s pitching elbow during his physical examination, multiple industry sources told The Post.

Rocker’s camp disagrees with those concerns, citing the pitcher’s durability at Vanderbilt, leading to a stalemate as Sunday’s 5 p.m. signing deadline approaches.

Rocker, whom the Mets drafted 10th overall, had agreed to a $6 million signing bonus on draft day pending the physical. The two sides could either sign off on a smaller figure, part ways altogether, or move forward with the original deal if the Mets determine that he’s worth the risk.

If an agreement can’t be reached, Rocker could return to Vanderbilt for his senior year, aim to get selected even higher in 2022 and earn outside money through the NCAA’s name, image and likeness allowance in the meantime.
