Source: Chris Olave (concussion) not expected to play vs. Bengals 11:20 PM ET ESPN New Orleans Saints wide receiver Chris Olave is not expected to play Sunday against the Cincinnati Bengals due to concussion symptoms, a source told ESPN's Adam Schefter. Olave, who was listed as questionable entering Sunday, got hurt after appearing to be briefly knocked unconscious when his head was slammed into the turf during a TD catch in the third quarter of New Orleans' 39-32 win over the Seattle Seahawks last Sunday. He was initially taken to the sideline medical tent for a concussion evaluation before going to the locker room and did not return. The absence further depletes an already thin corps of receivers. New Orleans already is playing Sunday's game without wide receivers Michael Thomas , Jarvis Landry and Deonte Harty , who have all been ruled out through injury. Andy Dalton , meanwhile, will start at quarterback for the Saints on Sunday after Jameis Winston was deemed not ready to play after returning to practice following a two-week absence caused by a back injury.
