The team made the announcement late Friday and because the 42-year-old Glavine has been plagued by the injury all season, there was immediate speculation about whether he would end his career.
He experienced elbow pain in Thursday's 11-7 loss to the Chicago Cubs when he gave up seven earned runs and seven hits in four innings.
"He was sore when he came out of the game," General Manager Frank Wren said on the team's Web site. "We'll evaluate it day-to-day. I think his performance was a result of what he was feeling."
"I don't think he really wanted to go on (the disabled list)," Manager Bobby Cox said. "But we're kind of in a bind."
Glavine, a 303-game winner in 21 major league seasons, was unavailable for comment.
