Former Red Sox pitcher Josh Beckett is unsure whether he will ever pitch again.

Beckett, whom Boston traded to the Dodgers late last season, has been on the disabled list since May 15 with a groin injury. According to the Los Angeles Times, he has felt numbness in his pitching hand for about a month, and when asked if he thought the injury might be career-ending, he voiced concerns.

"Any time something like that happens to your arm or you start losing feeling and stuff … you think about it for sure," Beckett told the Times. "I don't really want to think like that right now. I want to think about figuring out a way to deal with this."

Beckett, 33, is expecting to have results of an MRI Monday that will be examined by a nerve specialist.

"I'm concerned," he said. "I've never dealt with anything like this for this amount of time. We'll just have to see what happens there."

Beckett is 0-5 with a 5.19 ERA this season and is signed through the 2014 season.
