Tulowitzki exited New York's 2-1 loss to the visiting Detroit Tigers on Wednesday after the third inning with a Grade 1 strain in his left calf, manager Aaron Boone said postgame.
Tulowitzki popped out in the second inning and exited one inning later. Second baseman Gleyber Torres moved to shortstop to replace Tulowitzki with Tyler Wade entering at second base. The Yankees said Tulowitzki was being taken to nearby New York Presbyterian Hospital for further tests.
Signed to a one-year free-agent contract in January following a workout for teams, Tulowitzki is 2-for-11 on the young season with a home run.
Tulowitzki, 34, missed all of last season and the final two months of the 2017 season with a heel injury while with the Toronto Blue Jays. Before appearing in New York's Opening Day lineup, he had not played in a game since July 28, 2017.
The five-time All-Star shortstop was signed by the Yankees to fill the void left by Didi Gregorius, who had Tommy John surgery on his throwing elbow in October. He is expected to be out until June or July.
Despite being only six games into the 2019 season, the Yankees already have dealt with plenty of injuries. Veteran southpaw starting pitcher CC Sabathia was placed on the 10-day IL as he recovers from heart and knee procedures this offseason. He just finished serving a five-game suspension for throwing at a Tampa Bay Rays batter in September.
Other injured Yankees include outfielders Giancarlo Stanton (biceps strain) and Aaron Hicks (back), third baseman Miguel Andujar (shoulder), starting pitcher Luis Severino (shoulder) and reliever Dellin Betances (shoulder).
