The 24-year-old slugger, an American League Rookie of the Year runner-up, had undergone tests on his right shoulder ahead of the team's series opener Monday. Ahead of the game, he learned he had a small labrum tear and would need treatment for a few weeks before stepping foot on a baseball diamond.
According to ESPN, Andujar's injury was going to be treated conservatively and he was tentatively placed on a 10-day injured list. However, officials are now saying he will likely miss the majority of April's games and could even require season-ending surgery.
"Surgery could be in play, which would obviously compromise his season. There is some optimism that if treated conservatively, he can respond and come back and play good," Yankees manager Aaron Boone said after the Yankees' victory over the Detroit Tigers on Monday, ESPN reports. "We'll know that in a couple of weeks."
Andujar sustained the injury while diving into third base on a pickoff attempt during Sunday's game against Baltimore.
He joined a long list of sidelined Yankees that includes pitchers Luis Severino, Dellin Betances, Jordan Montgomery and Ben Heller, shortstop Didi Gregorius and outfielder Jacoby Ellsbury; pitcher CC Sabathia is set to be added to the injured list Wednesday, after he completes a suspension for hitting a batter with a pitch last September. Outfielder Giancarlo Stanton also strained his left biceps taking a swing on Sunday.
That means nearly half of New York's starting lineup is on the sidelines four games into the season.
Boone said Andujar didn't show any immediate signs he was injured from Sunday's dive.
"He stayed in the game ... was able to do all his throws between innings," he explained to ESPN.
It was during a pregame workout that he noticed Andujar was hurting — opting not to retrieve routine ground balls. Andujar later agreed to get an MRI to see what was going on.
In the interim, infielder/outfielder Tyler Wade agreed to take Andujar's spot in Monday's game.
Andujar, who made his professional baseball debut in 2017, is a huge asset to the team. Last season, the 6-foot, 215-pound athlete hit 27 home runs, 47 doubles and 92 RBI, according to Fox Sports.
