He will rest it for a few days and hope to avoid a stint on the disabled list.
"We're trying to get rid of it as fast as possible," Lidge said Monday night. "It's frustrating, but I missed a few games last year at the start of the season, and when I came back I felt great. If I have to do the same thing this year, miss a couple of games, that's OK."While he says an MRI shows there is no structural damage, he has felt discomfort since the Colorado series (April 10-12).
Lidge has four saves, one blown save and an ERA of 7.27 in his nine appearances this season.
