Red Sox Place John Lackey Placed on 15-Day Disabled List, Scott Atchison Recalled From Pawtucket

The Red Sox are about to do some more rotation shuffling.

The Sox placed right-hander John Lackey on the 15-day disabled list on Monday night with a right elbow strain. Right-handed reliever Scott Atchison was recalled from Triple-A Pawtucket to take Lackey's roster spot.

It's still unknown who will take Lackey's spot in the rotation, as he was scheduled to pitch against the Orioles on Tuesday at Fenway Park.
