75 percent chance Brandon Marshall, Alshon Jeffery do not play, per Adam Schefter

The Chicago Bears starting wide receivers, Brandon Marshall and Alshon Jeffery are both questionable for Sunday Night Football against the San Francisco 49ers, and are game time decisions. However, according to Adam Schefter, there is a significant chance neither receiver plays in the game.

Major questions about Bears WRs, Marshall and Jeffery. One source said "75 percent" sure neither plays tonight. Bears signed two PS WRs Sat.

The Bears promoted two wide receivers from their practice squad on Saturday. Marshall and Jeffery are question marks, but they are also likely to be without Josh Morgan. Given Morgan's expected absence, I still think we end up seeing Marshall play. The Bears could decide to play it safe and sit both, but with the prospect of falling to 0-2 coming out of the gates, I just have a hunch at least Marshall plays.

Whatever the case, this is seemingly a boost for the 49ers own injured cornerback depth. Tramaine Brock is questionable for the game with turf toe, and seems unlikely to play. Chris Culliver suffered a concussion last Sunday, but all indications are that he will play. It would likely be Culliver and Perrish Cox starting, with Jimmie Ward in the nickel, and Dontae Johnson and Chris Cook as the backups on the outside. If the 49ers ever go into dime against the Bears, my guess is Johnson comes in on the outside, and Cox moves to the dime role opposite Ward.
