Washington, DC (SportsNetwork.com) - Philadelphia Phillies pitcher Cliff Lee is back on the 15-day disabled list after leaving Thursday's start against the Washington Nationals.
Lee exited Philadelphia's 10-4 victory after throwing a pitch to Denard Span with two outs in the third inning.
"I was hoping it was a little twinge that would go away, and it progressively got worse as the game went on," Lee said after the game. "My last five or six pitches I felt like at any moment something could snap ... and obviously I didn't want that to happen."
The veteran left-hander was making just his third start after being activated off the disabled list on July 21. He had missed two months with an elbow strain.
Lee is expected to be examined Saturday, but his 2014 season could be over. He was initially diagnosed with a left flexor pronator strain.
In 13 starts this season, Lee has posted a 4-5 record with a 3.65 earned run average.
The Phillies recalled pitcher Cesar Jimenez from Triple-A Lehigh Valley after Thursday's game to replace Lee's roster spot.
