PHILADELPHIA -- Phillies closer Brad Lidge received a cortisone shot in his injured right elbow before Monday's game, on the advice of renowned surgeon Dr. James Andrews and team physician Dr. Michael Ciccotti.

Andrews reviewed Lidge's MRI results taken Thursday, and he and Ciccotti made the decision for treatment with a cortisone shot -- the second such shot in his elbow in two months.

Lidge went on the 15-day disabled list Saturday, but is eligible to come off May 25.

"It's a relief," Lidge said. "I'm fortunate that it's just the joint cleared up and they've got ways to treat it. Hopefully as soon as I get off the DL, I'll be able to throw in games."

Lidge had surgery on the elbow in the offseason and spent the first month of the season on the disabled list. He was activated for four games before he felt the elbow stiffen up while playing catch last Monday in Colorado.

He got an MRI in Philadelphia on Thursday, which showed no loose bodies or damaged ligaments.

"They said it is possible that this thing could happen after surgery, that setbacks are possible," Lidge said. "They really said you shouldn't have to deal with any more after this -- it's kind of the last stage to getting to 100 percent. It happened, and hopefully now I'll be able to bounce back and get back up and get into midseason form."

Lidge will wait until the shot is absorbed for two days, and then he is expected to begin throwing. He said that he and Ciccotti will discuss possibly using a joint lubrication injection if it's necessary down the road.

"You don't have to miss any time, you can kind of get that as you're going," Lidge said of the lubrication injection. "I haven't done that yet, but it's something we can do. It really can kick-start the joint and get it back to normal real fast."

Right-hander Jose Contreras will continue to serve as the club's closer in Lidge's absence.

With Utley out, Polanco moves to second

PHILADELPHIA -- Phillies second baseman Chase Utley was scratched from Monday's game with flu-like symptoms. Placido Polanco started at second base, with Greg Dobbs moving to play third.

Jimmy Rollins, who was activated Monday, hit in Utley's No. 3 spot in the order.

Manager Charlie Manuel said Utley had been playing through some illness for the past few days but hadn't mentioned it to anybody.

"He hadn't said anything about it," Manuel said. "He'd been feeling ill the past couple of days. He didn't say too much about it."

Utley hit .333 with a home run and four RBIs during the team's six-game road trip. Monday was just the second game he's missed this season.

Happ throws side session, reports no pain

PHILADELPHIA -- Phillies left-hander J.A. Happ threw 20 pitches in a bullpen side session on Monday and reported no pain in his strained left forearm.

It was the first time Happ threw off a mound since he suffered a setback doing so two weeks ago. Phillies pitching coach Rich Dubee was optimistic about the outcome of the session.

"Today was a big hurdle," Dubee said. "This is where we got to last time, and he didn't respond very well. He responded much better today."

Happ, who has been out since April 16, will rest for the next few days and then, assuming no setbacks, will throw another bullpen session in three or four days. He threw all fastballs on Monday.

"[Tuesday] will be a good test," Dubee said.

Ruiz returns to lineup

PHILADELPHIA -- The Phillies had catcher Carlos Ruiz back in the lineup Monday after he missed three games with a sprained right knee.

Ruiz, who leads the team with a .345 average and .472 on-base percentage, sustained the injury Wednesday against Colorado. He caught a bullpen session with Jamie Moyer on Sunday.

"I'm happy to be back in the lineup," Ruiz said.

Phillies manager Charlie Manuel said he still may be cautious with how he will work him.

"We'll play him today, see how he reacts," Manuel said. "We'll take it day by day for a while."

Backup catcher Paul Hoover hit .417 with six runs scored in the three starts he made in Ruiz's place. Brian Schneider (left Achilles strain) will be eligible to come off the 15-day disabled list next Monday.
