PHILADELPHIA -- Dodgers Cy Young Award winner Clayton Kershaw has been dealing with plantar fasciitis for the past week, manager Don Mattingly said Tuesday.

Kershaw took a painful step going to first base Monday night, and Mattingly said it's "a little plantar fasciitis. He took a funny step and just felt it."

Mattingly said Kershaw has been receiving treatment for the condition for "at least a week."

"He says he doesn't feel it at all [while pitching, only when running]. They're trying different tape and things at night to help it go away," Mattingly said.

Kershaw allowed three runs in a seven-inning no-decision Monday night against the Phillies.

Guerra has surgery for small meniscus tear

PHILADELPHIA -- Dodgers reliever Javy Guerra underwent arthroscopic right knee surgery Tuesday to repair a small tear of the lateral meniscus and will be sidelined four to six weeks. Dodgers team physician Neal ElAttrache performed the surgery.

Guerra was placed on the disabled list Monday with an injury believed to be sustained when he was struck by a Brian McCann line drive in the jaw on April 25. After contact, Guerra spun toward his right and his spikes might have stuck in the ground while he twisted his knee. He remained in the game, suffered a blown save and two weeks later lost the closer's job to Kenley Jansen.

"Sue said the doc was happy with it," manager Don Mattingly said, referring to trainer Sue Falsone. "There wasn't any other damage. He'll be back playing catch quick. A few days and he'll be throwing again."

Guerra was the surprise of the bullpen last year, called up from Double-A in May and inheriting the closer's job from a struggling and injured Jonathan Broxton. Guerra saved 21 games as a rookie with a 2.31 ERA.

But even before his injury this season he was hit harder and more often than last year. Guerra was a fourth-round Draft pick in 2004 who overcame Tommy John surgery in the Minor Leagues.

Uribe set to begin three-game rehab stint

PHILADELPHIA -- Dodgers third baseman Juan Uribe will fly back to Los Angeles on Wednesday and start a three-game rehabilitation assignment with Class A Rancho Cucamonga, with his anticipated activation from the disabled list Monday.

Manager Don Mattingly said that Uribe, sidelined since May 14 with an arthritic left wrist, will regain his starting job when he returns.

Mattingly has started five other players at third base this season, and the team has had the most success with Adam Kennedy there, going 12-4. Jerry Hairston, Justin Sellers, Elian Herrera and Ivan De Jesus Jr. have also started at third for the Dodgers.

In other medical news, Mattingly said Sellers' recovery from a herniated disk in his back is going slowly with continued tingling in his toes; Ted Lilly continues treatment with medical director Stan Conte in Los Angeles; Mark Ellis continues his recovery from lower leg surgery; and Matt Guerrier reported improvement in his elbow tendinitis after receiving another platelet-rich plasma injection last week.
