TORONTO -- Boston left-hander David Wells will be placed on the 15-day disabled list because of a sore right knee, Red Sox manager Terry Francona said Tuesday night.
Wells left his last start after taking a line drive off his knee. He experienced soreness while throwing on flat ground Monday.
Right-hander David Pauley will start for Boston on Wednesday in Wells' absence.
Pauley went 2-3 with a 2.39 ERA in 10 starts with Double-A Portland.
"It's a pretty significant jump. If I just stick to how I know how to pitch I think I will be all right," Pauley said.
The 43-year-old Wells has pitched just twice this year. He underwent surgery in the offseason on his right knee and started the season on the disabled list. He went back on the disabled list after sprained his right knee in 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 hit a line drive off the same knee.
