Green Bay Packers wide receiver Greg Jennings has been sidelined since he sustained a concussion Aug. 3 and it's not clear when he'll be able to practice again.
Jennings got a concussion in the Packers' "Family Night" scrimmage and hasn't been on the field since.
Packers coach Mike McCarthy said Tuesday that Jennings continues to be tested in accordance with the NFL's protocols for returning from a concussion, but needs more time to recover.
Although McCarthy and his assistants won't determine playing time until Wednesday, Jennings is considered unlikely to play in Thursday night's preseason game against Cleveland at Lambeau Field.
McCarthy says, "We're not going to put him back out there until we're 100 percent that he's clear."
