Stanton, whose status for Opening Day is in doubt, said he's not sure how long he will be shut down from baseball activity and did not know what his timeline was for a potential return, according to Lindsey Adler of The Athletic.
Explaining that the injury occurred while running in the outfield on a redirect, Stanton -- who noted that he had increased his flexibility and mobility work the day of the injury -- said he was "not surprised" to hear the results of his MRI.
Stanton was also annoyed at the fact that getting hurt again "makes it seem like" he didn't take care of himself in the offseason, when he says the opposite is true.
Asked earlier this week if Stanton will be ready for the start of the regular season, Yankees manager Aaron Boone said "he will be down a bit."
Yankees GM Brian Cashman recently told SNY contributor Anthony McCarron that Stanton was "looking forward to reminding the fans of baseball that he's still an elite player."
Stanton played in just 18 games during the regular season in 2019 as he dealt with a calf strain and other injuries. He was not 100 percent when the playoffs began and played through the ALDS before being limited to just two games in the ALCS as the Yanks lost to the Astros in six games.
Along with the injury to Stanton, the Yankees are still without Aaron Judge, who is dealing with a shoulder issue.
