SANTA CLARA -- The Chicago Bears enter Sunday night’s game against the 49ers with just three healthy wide receivers – two of which were added to the 53-man roster on Saturday.
Brandon Marshall and Alshon Jeffery are listed as questionable, and a decision on their availability will not officially come until 90 minutes prior to the 5:30 p.m. kickoff at the regular-season opener at Levi’s Stadium.
Marshall (ankle) did not practice at all this week. Jeffery (hamstring) did not practice Wednesday or Thursday but saw limited work during Friday’s practice.
ESPN’s Adam Schefter reported Sunday morning there is a "75 percent" chance neither will play. And former 49ers wide receiver Josh Morgan is not expected to be available due to a groin injury. Morgan is listed as “doubtful” for the game.

Marshall and Jeffery formed the top receiver combination in the NFL last season. Marshall caught 100 passes for 1,295 yards and 12 touchdowns, while Jeffery had 89 receptions for 1,421 yards and seven touchdowns.
Santonio Holmes, a nine-year veteran, is the only veteran Bears wide receiver whose status is not in doubt. He caught two passes for 21 yards in Chicago’s season-opening loss to the Buffalo Bills.
On Saturday, the Bears promoted wide receiver Josh Bellamy (Louisville) and Chris Williams (New Mexico State) to their 53-man roster. Neither player has a reception in an NFL game. The Bears also added center Taylor Boggs (Humboldt State) with veteran Robert Garza sidelined with an ankle injury.
Meanwhile, the 49ers expect cornerback Chris Culliver to play Sunday night as he returns from a concussion he sustained in the season-opening victory against the Dallas Cowboys. Perrish Cox is expected to start in place of Tramaine Brock, who is out with a big toe sprain.
