TORONTO -- Red Sox left-hander David Wells will miss a turn in the rotation because of a sore right knee.
Wells left his last start after taking a line drive off his knee. He'll miss his scheduled start on Wednesday. He experienced soreness while throwing on flat ground Monday.
"It was pretty sore," Boston manager Terry Francona said. "But we're not going to DL him yet either."
Wells threw 15 to 20 pitches before shutting it down. Francona declined to say who will start Wednesday.
The 43-year-old Wells has pitched just twice this year, starting the season on the disabled list and going back on with a sprained right knee after an April 12 start in which he gave up seven runs in four-plus innings. In his last start on Friday, he left in the fifth inning when Travis Lee lined one off the same knee.
Wells reached for the inside of his knee and fell while wincing in pain. He then rolled over onto his front side.
