Strop (knee) strained his right groin Thursday, which will delay his recovery from left knee surgery, Patrick Mooney of CSN Chicago reports.

EDGE Analysis

Strop threw a bullpen session earlier in the week and was though to be nearing a return from an August 11 arthroscopic procedure on his knee. This latest news is expected to delay his return by roughly two weeks, but it's far from a devastating setback for the right-hander, who's still anticipating pitching out of the bullpen later in the month, prior to the postseason.
