Grisham was removed from Friday's game against the Blue Jays with right hamstring tightness, Gary Phillips of the New York Daily News reports.
Grisham seemingly tweaked his hamstring while rounding first base after collecting an RBI knock in the sixth inning, and he was taken out of the game immediately afterward. With Jasson Dominguez (shoulder) and Giancarlo Stanton (calf) both still on the IL, Jose Caballero would likely have to move to the outfield if Grisham needs to miss a start or two.
