How Concerned Should We Be About Lowell?

Mike Lowell sat out most of the last two interleague series to rest his ailing hip. He will now be receiving injections to lubricate his hip joint. If he doesn't respond in a few days he might go to the DL:

“I guess it could happen,” Francona said. “I don’t think we want to, and I don’t think he wants to. But if he didn’t respond to this, it’s probably something we’d have to think about it. But I don’t think that’s our goal, for sure. . . . Because there’s a lot of season left to go, we’d rather try to let him take a deep breath or regroup. We just want him to be able to go out and play rather than drag it, or when he makes a move, feel it so much.”

If Lowell does go on the DL then Kotsay would take over at first and Youk would go to third. Lowrie can play third when he gets back and Green is also an option but Lowell's bat would surely be missed.
