Dustin Pedroia has doubts about whether he'll be able to return this season as he continues to recover from major reconstructive knee surgery in the offseason.
Pedroia, 34, returned to the Boston Red Sox on May 26, but was back on the disabled list with knee soreness by June 2.
"I've healed quick with every other injury I've had. But this is obviously different," he said. "You can't risk it. If I come back too early and the graft fails, then that's it."
Earlier this week, Alex Cora said he still expects the infielder to play again this season, but Pedroia said he'll know more "in 4-5 weeks" before making that determination.
"I'd love to play right now. But I can't," Pedroia said. "I'm going to be back for good if I let it heal. That's it. I've got to let it heal. ... I can't do anything about time."
