SANTA CLARA, Calif. -- The Chicago Bears announced receivers Brandon Marshall and Alshon Jeffery will play Sunday night against the San Francisco 49ers after the duo tested their respective injuries during pre-game warmups at Levi's Stadium.
The club officially listed them as questionable heading into the game.
The Bears held out Marshall from Friday's practice, as he's been hobbled with a sore right ankle. Jeffery participated in practice in a limited capacity on Friday, and took part in team drills. But Bears coach Marc Trestman said both players' potential availability would be game-time decisions.
During pre-game warmups, Marshall and Jeffery spent several minutes with strength and conditioning coordinator Mike Clark stretching and running routes to test whether they could handle the rigors of a live game. As the duo warmed up, Trestman huddled at the 5-yard line near the North end zone with head athletic trainer Chris Hanks, general manager Phil Emery, offensive coordinator Aaron Kromer, offensive quality control coach Carson Walch and quarterbacks coach Matt Cavanaugh to watch the receivers and presumably make a decision as to whether they'd play.
Marshall and Jeffery suffered their injuries during the second half of the club's season-opening loss to the Buffalo Bills. Marshall said on Thursday he planned to play, while Jeffery seemed a little more measured about his prospects.
During warmups, it appeared that Marshall was able to go full speed. He ran routes and made several cuts and didn't appear to be in any discomfort. Jeffery, meanwhile, appeared to be favoring his left hamstring during warmups. There's a chance that both Marshall and Jeffery won't be able to complete the entire game. But such a scenario appeared more likely for the latter than the former.
If one or both can't finish the game, look for Santonio Holmes and Josh Bellamy to serve as replacements. The Bears spent extra time working with Holmes and Bellamy during the week of practice leading up to Sunday in anticipation that Marshall and Jeffery might not be available.
The Bears also activated Chris Williams off the practice squad, and he's active for Sunday's matchup.
In other news, the Bears announced that receiver Josh Morgan, linebacker Khaseem Greene, center Roberto Garza, left guard Matt Slauson, tackle Charles Leno Jr., and defensive ends David Bass and Cornelius Washington will be inactive for Sunday's contest.
Brian de la Puente and Michael Ola will man Garza and Slauson's spots in the starting lineup.
