Panthers head coach Frank Reich said that Chark was absent Wednesday due to an unspecified injury, Joe Person of The Athletic reports.
Reich declined to expand on Chark's status, but at the very least, the starting wideout looks at risk of missing Friday's preseason finale against the Lions. The Panthers have already been working without Terrace Marshall (back) and Laviska Shenault (concussion) at practice, so the team could look to sign another wide receiver.
