Head coach Lovie Smith said he wouldn't be surprised if Harris had to sit out the game at Pittsburgh. If Harris is unable to go, the Bears have three players that could replace him in the starting lineup with Mike Green being the top option.
Last year the Bears had 42 games lost by defensive starters to injury. Amazingly if Harris is unable to go, it would be the first game lost to injury for the unit this year.
SLB Hunter Hillenmeyer fractured his thumb against Green Bay, but after having a cast put on his right hand he finished the game and is expected to start vs. the Steelers.
Wide receiver Bernard Berrian caught his first passes since suffering a torn thumb tendon Oct. 23 and had a huge impact even in the Bears' struggling passing game.
The Bears' fastest active receiver had three catches for 59 yards. The Bears had only three other catches for nine total yards in the game.
"Having more speed in there as a big-play threat is huge for us," Bears offensive coordinator Ron Turner said.
Berrian's biggest plays were two go patterns along the sidelines in which quarterback Kyle Orton hit him for gains of 34 and 18 yards. The 34-yarder set up a Robbie Gould field goal in the second quarter to close the Bears' deficit to 7-6. The 18-yarder put the Bears at Green Bay's 25 and set up Gould's 35-yard field goal in the fourth quarter for a 12-7 lead.
"It feels real good, " Berrian said. "It's been a long time coming. I've been out for a while and I feel that if you get an opportunity to do something, it's up to you to make those plays."
Robbie Gould has been dependable on short field goals, making 13-of-14 inside 40 yards, but Gould failed on a chance to put his name in the Bears' record book and silence some critics during the fourth quarter Sunday.
Gould made field goals of 21, 40, 25 and 35 yards to give the Bears a 12-7 lead, but had a chance to give them breathing room with 4:09 left in the game on a 43-yarder into the wind. He came up short. His first field goal after replacing Doug Brien was a 44-yarder, but he is now 2-for-6 from 40 yards and beyond.
"You want to make it," he said. "It's one of those things that you've heard for the past several weeks, 'well, Robbie's only hit short field goals.'
"It's one thing to go out there and hit short field goals because that's what you're being given. I wanted to hit a little bit longer field goal to let people know that I could do it. But it just feels good to go out there and get another win."
