Yankees' Severino to undergo MRI after shoulder rehab stalled

New York Yankees manager Aaron Boone said Monday that right-hander Luis Severino will undergo an MRI and see a team doctor on Tuesday because his injured shoulder doesn't feel quite right, Brendan Kuty of NJ.com reports.

Severino's rehab has been stalled for about a week and he's only been throwing on flat ground at 120 feet, according to Kristie Ackert of the New York Daily News. The Yankees said they were waiting for him to tell the team he's ready to go on the mound.

Severino has been sidelined since early March with soreness in his right rotator cuff. The club was expecting him back at some point in May, but Boone said it's unclear whether the ace has done more damage to his shoulder.

"The original testing we did with him (led) us to be pretty confident," said Boone, according to Kuty. "But we've got to make sure he's right.

"The fact he hasn't been able to graduate from flat-ground throwing yet to the mound, we've got to answer those questions the best we can. Cross every 'T,' dot every 'I,' make sure we're getting all the answers."

New York signed the 25-year-old to a four-year, $40-million extension in February after back-to-back All-Star seasons in 2018 and 2017.

Injuries have decimated the Yankees early in the 2019 campaign, with Severino, Giancarlo Stanton, Miguel Andujar, Aaron Hicks, CC Sabathia, Dellin Betances, Ben Heller, Jordan Montgomery, Jacoby Ellsbury, and Troy Tulowitzki on the injured list.

Despite the health struggles, the team has a 5-4 record with a 2.89 ERA (6th in MLB) and 20 home runs (3rd).
