Cliff Lee will be placed on the 15-day disabled list with a mild elbow strain, and the Philadelphia Phillies are relieved to learn the injury wasn't more serious.

Lee might be able to return as soon as he's eligible to come off the DL, general manager Ruben Amaro Jr. said late Tuesday.

When Lee underwent an MRI on Tuesday in Philadelphia, there were concerns the left-hander might become the latest major league pitcher to be sidelined by a serious injury.

Lee pitched 6 2-3 innings in a win over Cincinnati on Sunday. He has experienced mild elbow discomfort for the past three weeks.

The veteran was diagnosed with a grade one/two strain of his flexor tendon. Amaro declined to say who will start for Lee on Saturday against the Los Angeles Dodgers.
