Conner is dealing with a pulled hamstring and has been sidelined during OTAs as a result, Mark Kaboly of DKPittsburghSports.com reports.
Conner's hamstring injury isn't believed to be serious, but he may be sidelined until next week's trio of OTAs, which start back up again on Tuesday. The Pittsburgh product, who overcame both a torn MCL and Hodgkins lymphoma during his collegiate career, is no stranger to adversity as he'll battle for the No. 2 spot at running back upon his return to the practice field.
