Source: Bears WR Alshon Jeffery expected to play vs. Cowboys

Chicago Bears receiver Alshon Jeffery, listed as questionable with a knee injury, is expected to play Sunday night against the Dallas Cowboys, a source told ESPN NFL Insider Adam Schefter.

Jeffery, the Bears' leading receiver, caused a minor stir on Thursday when he missed practice because of a knee injury -- he had been limited on Wednesday -- but he was back out there on Friday, albeit again in limited fashion.

Jeffery has been the Bears' only consistent playmaker on an offense that ranks second worst overall, third worst in points scored and fourth worst in passing offense.
