NEW YORK -- Yankees third baseman Josh Donaldson will be out for "a couple more weeks" after suffering a Grade 1 hamstring strain during his rehab assignment.
"He's doing pretty well," said Yankees manager Aaron Boone. "He's getting around well, but there's something there."
Donaldson's return appeared to be imminent before the setback. The former MVP planned to be with the Double-A Somerset Patriots for a day, but left the game after five innings and three at-bats upon experiencing tightness.
Upon returning from his rehab assignment, Donaldson underwent an MRI.
"I'm bummed out," Donaldson said.
