Pittsburgh Steelers wide receiver JuJu Smith-Schuster now is not expected to play Sunday night against the Buffalo Bills after he aggravated his knee injury during practice on Thursday, a source told ESPN's Adam Schefter.
Schefter has missed the past three games with the knee injury and had been eyeing a return Sunday night.
Schuster, along with running back James Connor, was injured Nov. 14 against the Cleveland Browns. Schuster injured his knee and suffered a concussion on the same play in that game.
Connor has an injury to the AC joint in his shoulder.
