Jeffery left Sunday's game after the first play of the fourth quarter when he got inside position on Jaguars cornerback Rashean Mathis to score on a 10-yard slant. Mathis had tight coverage, but quarterback Jay Cutler made an accurate throw and Jeffery was taken to the turf upon making the catch.
"I could have kept playing," he said. "I'm confident it's not serious."
Jeffery's hand appeared rather swollen. He entered the weekend as the leading rookie wide receiver in the NFL with 12 catches for 164 yards and scored his second touchdown of the season while making one other reception for 10 yards in the game.
"He really is a big part of our offense," said Brandon Marshall, who had 12 receptions for 144 yards. "Tried to get him going a little bit this week. He had a big score for us. Got us going in the second half, but we're so deep in the wide receiver room it doesn't matter if it's Alshon or me or Devin (Hester), we've got a guy who can step up and play."
Earl Bennett was inactive for the second straight game with an injured left hand. He had a plastic brace protecting the thumb and first two fingers. The plan is for him to be ready to face the Lions Oct. 22.
Heat of the moment: Intent on stopping Jaguars running back Maurice Jones-Drew, the Bears used an extra defensive tackle as Matt Toeaina was active for the first time since the season opener. The warm weather — 88 degrees at kickoff — contributed to the plan to rotate linemen. Toeaina played throughout and the goal of stopping Jones-Drew was accomplished as he had only 56 yards on 12 carries — 27 coming on a trap in the fourth quarter.
The heat affected more than just the players in the trenches.
"I've lived here almost all my life and I am still not used to it," Marshall said. "I've got Bear blood in me now."
Terry's take: Fox's Terry Bradshaw continued the analysis of Cutler's sideline demeanor, criticizing him for the incident last Monday at Dallas.
"I would show respect to the head coach and offensive coordinator," Bradshaw said. "I would never do, Jay, what you did to Mike Tice. No matter if he was in your ear the whole time screaming and hollering. You know you've got millions of people watching. If I were you, I would learn how to be a little bit nicer. I know you don't care and nor do I care if I ever sit down and do an interview with you — which I have yet to do. Maybe there's a reason for that. I like everybody. I'd like to like you, but right now I don't like you. Grow up young man."
Inactives: Former first-round draft pick Chris Williams was inactive for the second straight game. Fullback Evan Rodriguez missed his second straight game with a minor ACL sprain in his left knee, but with the off week coming, he could return against the Lions Oct. 22. Running back Kahlil Bell, guard Edwin Williams and defensive linemen Nate Collins and Cheta Ozougwu also were inactive.
Extra points: The coaching staff left Matt Forte in the game just long enough for him to reach 107 yards, the first time he has topped 100 since last Nov. 7 at Philadelphia. ... Corey Wootton had two sacks to give him 3½ and he also has two forced fumbles on the season. … Linebacker Lance Briggs had a sack for the first time since Dec. 20, 2010.
