Pineda is now scheduled to undergo a dye contrast MRI exam on Tuesday in New York, at the direction of team physician Christopher Ahmad. Manager Joe Girardi said that a scheduling conflict pushed back Pineda's examination.
"He's going to see the doctor [on Tuesday] and go through all his tests tomorrow," Girardi said. "At some point tomorrow evening, we should have something."
Pineda has been on the disabled list, retroactive to March 31, with what the team has termed right rotator cuff tendinitis. He suffered a setback during Saturday's start, cutting short his outing after just 15 pitches.
