Tom Glavine went back on the Atlanta Braves' disabled list on Friday, a day after the two-time NL Cy Young Award winner was hit hard in his first start since June 10.

Trying to overcome an elbow injury, Glavine gave up seven runs, seven hits and four walks in an 11-7 loss to the Chicago Cubs on Thursday night. The loss may have ended his season, and he has not said how the setback could affect his hopes of pitching in 2009.

The 42-year-old Glavine, who has a torn flexor tendon in his left elbow, sat out two months while hoping to avoid surgery. He experienced more discomfort on the mound, resulting in decreased velocity.

Longtime teammate Chipper Jones said it was not a surprise to see Glavine forced back to the disabled list.

"I figured he would be," Jones said. "When he's throwing his fastball 82 miles per hour ..."

Braves general manager Frank Wren said the discomfort Glavine experienced after the game and on Friday "was a little more than he has had in the past."

"His stuff was down a little from what we saw in the rehab starts," Wren said. "Tommy was trying to get through it, but he didn't feel as good as he liked."

Wren said "we're still evaluating" how the setback affects Glavine's status for this season and in 2009. Wren said Glavine would consult with the team's medical staff on Saturday.

Could the setback end Glavine's career?

"I just don't think we know enough to say that kind of thing," Wren said.

Glavine has made only three trips to the disabled list in his 22-year career _ all this season. He spent two weeks on the disabled list in April with a hamstring injury.

Glavine said his elbow "felt pretty good" during Thursday night's game. Speaking with reporters after the game, he added "It's a little sore now. We'll see how it feels tomorrow and the next day."

Glavine, who won his 300th game last August at Wrigley Field while pitching for the Mets, was attending to a family matter and was not at Turner Field before Friday night's game against San Francisco.

"I talked with him and he's disappointed," right fielder Jeff Francoeur said.

"I don't think his arm bothers him so much when he's pitching as when he's done. It's tough for him. I know he's hurting for the first time in his career."

Glavine is 2-4 with a 5.54 ERA in 13 games. He is 305-203 in his career.

Glavine re-signed with the Braves this year after five seasons with the Mets. He pitched with the Braves from 1987-2002 and won at least 20 games five times.

Atlanta purchased the contract of right-hander Matt DeSalvo from Triple-A Richmond. DeSalvo was 2-11 with a 4.60 ERA in 32 games, including seven starts, at Richmond. Manager Bobby Cox said DeSalvo will pitch in relief.
