LAKE FOREST, Ill. -- The Chicago Bears officially listed receivers Alshon Jeffery (hamstring) and Brandon Marshall (ankle) as probable for Sunday’s matchup against the Tampa Bay Buccaneers at Soldier Field.

The club ruled out defensive end Trevor Scott (knee), receiver Chris Williams (hamstring) and linebacker Darryl Sharpton (hamstring), while listing right tackle Jordan Mills (ribs), guard Eben Britton (illness), and cornerback Demontre Hurst (knee) as questionable.

Rookie defensive tackle Ego Ferguson (illness) is also probable.

Williams’ absence against the Bucs will set the stage for Marc Mariani to take over as the club’s primary kickoff and punt returner.

“He’s worked hard this week and he’ll be returning for us, both punts and kickoffs,” Bears coach Marc Trestman said. “He’s had a reliable week, picked up things he needed to pick up to get us going in the return, and we’re all feeling good about that.”

Mills’ availability, meanwhile, remains in question. If Mills can’t play against the Bucs, Michael Ola will replace him at right tackle. Mills has missed two of the team’s last three games, including last week’s win over the Minnesota Vikings.

“Right now we’re just going to see where he’s at,” Trestman said of Mills. “We’re not going to get into that point right now, just see where he is and make that determination over the next 48 hours.”
