The Yankees announced that Tauchman would return to New York on Monday for an MRI and evaluation.
Tauchman limped off after fielding a routine single hit by Boston's Brock Holt in the fourth inning. He stopped just before the ball reached him and was favoring his left leg.
Tauchman, who hit a two-run homer in the top of the inning to give New York a 6-2 lead, was able to walk on his own back to the dugout and was replaced in left by Cameron Maybin.
The 28-year-old Tauchman has been a breakout performer for the banged-up Yankees. He's hitting .277 with 13 home runs this season.
