Lackey will head to the 10-day DL due to plantar faciitis, Jesse Rogers of ESPN Chicago reports.

EDGE Analysis

Lackey pitched through the foot troubles in his Wednesday start against the Rays, where he turned in a quality outing with six innings of three-run ball. Now on the DL, Lackey won't actually have to miss a start due to the upcoming All-Star break -- his next turn in the rotation would come after the 10-day minimum has passed. The move will also clear up a roster spot for Kyle Schwarber, who was promoted back to the majors in a corresponding transaction.
