CINCINNATI -- Dodgers rookie right-hander Rubby De La Rosa will make his first Major League start on Tuesday night in Philadelphia, replacing Jon Garland, who is expected to be placed on the 15-day disabled list with right shoulder inflammation. Garland will join Vicente Padilla, who has a new/old injury.

Padilla, healed from an irritated nerve in his forearm, failed a pregame test when he was unable to pitch because of a recurring bulging disk in his neck.

Padilla said it is the same problem that limited him last year to one start after Aug. 16.

"I worked very hard to come back, and this is the result," said Padilla. "I felt my neck a little bit tight in my last rehab game [Wednesday], but I never imagined it would be this bad."

Garland, who pitched six innings Wednesday night in the Dodgers' 3-0 loss to Colorado in Los Angeles, complained during the game and did not accompany the club on the trip east.

Manager Don Mattingly said the back of Garland's shoulder has bothered him at least the past two starts. He underwent an MRI that showed no considerable change from the one taken during the offseason when he was signed to a one-year contract plus an option for 2012. Mattingly was vague about the timetable for Garland's return.

"His recovery is based on how he feels," Mattingly said. "It sounds like his shoulder was killing him, but he had been doing his normal throwing. Jon knows his body. He knows exactly how to take care of himself."

Garland is 1-5 with a 4.33 ERA and a four-decision losing streak, the lone win coming on April 20. He has 28 strikeouts and 20 walks in 54 innings.

He was signed to be a workhorse, having gone 10 seasons without a disabling injury. But in keeping with the Dodgers' injury-prone ways this year, Garland has been sidelined twice, the first being a strained oblique muscle he suffered in Spring Training.

The injuries will be costly for Garland. He receives a $3.5 million base salary this year with a $1 million signing bonus, but there are another $3.525 million in incentives this season if he pitches between 150-190 innings, plus an $8 million option for next year that would vest at 190 innings.

Padilla has been out since May 14 with irritation of the right radial nerve. He started the season on the disabled list after undergoing surgery in February to free that entrapped nerve.

De La Rosa, who has allowed one earned run in five big league innings, was 2-2 with a 2.93 in eight starts at Double-A Chattanooga before he was promoted to the Dodgers on May 24.

Furcal injures left side, expected to go on DL

CINCINNATI -- Los Angeles shortstop and leadoff hitter Rafael Furcal left in the third inning of the Dodgers' 2-1 loss to the Reds on Friday with a strained oblique muscle that is expected to put him back on the disabled list.

Furcal missed 37 games with a fractured left thumb he suffered while stealing third base in San Francisco and was activated on May 22. He was lifted for pinch-hitter Jamey Carroll in the top of the third against Cincinnati.

In the bottom of the second inning, Fred Lewis missed a sacrifice-bunt attempt and Dodgers catcher Dioner Navarro threw to second base when Jay Bruce drifted too far toward third. Furcal took the throw and threw to third base to get Bruce, but instead injured himself on the play.

Furcal flied out to left field in his only at-bat leading off the game. He is hitting .212 with two stolen bases and seven runs scored in 17 games.

This will be Furcal's sixth stint on the DL in his sixth year with the Dodgers.

The 33-year-old is the highest-paid Dodger at $14 million this year, with a club option for 2012 for $12 million that would vest if he reaches 600 plate appearances this year.

Furcal left the clubhouse by the time reporters arrived and was not available for comment.

Uribe, Hawksworth, Thames rehabbing injuries

CINCINNATI -- Disabled Dodgers infielder Juan Uribe began a Minor League rehab assignment, and reliever Blake Hawksworth and outfielder Marcus Thames resumed theirs Thursday night.

Uribe, out with a lower abdominal muscle, went 2-for-4 with a run scored for Class A Rancho Cucamonga against High Desert. Dodgers manager Don Mattingly said Uribe ran the bases well and could rejoin the club next week in Philadelphia. Hawksworth pitched a scoreless inning for Rancho Cucamonga, allowing one hit. Disabled May 11 with what originally was believed to be a strained groin, Hawksworth cut short a rehab assignment a week ago and underwent additional tests that revealed a hip injury. He received a cortisone injection a week ago and has resumed his rehab.

Mattingly said Hawksworth's rehab will require three or four more appearances to ensure that he really is healed.

Thames has concluded the Triple-A Albuquerque portion of his rehab from a strained quad muscle, and he has been transferred to Double-A Chattanooga so he'll be closer to rejoin the club when it plays in Philadelphia next week.
