Pre-Gamer: Bears at Lions

For so long, the Lions were the doormat of the NFC North, but this season has been different. They are 4-0 and actually favorites to win over Chicago on Monday night. That's the first time that has happened since 2005.

What do you need to know going into the game?

He's back! Chris Harris has missed the Bears last three games with a strained hamstring, but he is expected to play on Monday night. Considering how the Bears have struggled at safety, this is welcome news. He wrote a blog post just to say how much he can't wait, and his wife upped the ante. For every forced fumble, interception or fumble recovery that his husband causes in October, she will donate $1,000 to a breast cancer charity.

How will the offensive line hold off Suh? Between injuries and play-related decisions, the Bears have again failed to keep together a coherent offensive line. Though they played very well against the Panthers, they will have to deal with Ndamukong Suh and the frightening Lions D.

Comeback kids: Absolutely no lead is safe against the Lions. They engineered comeback wins against the Cowboys and Vikings, so the Bears cannot let up at any point in the game.

Stopping Megatron: Oh, Calvin Johnson. He is the reason that the Lions came within inches of beating the Bears in the opener last season, and he is one of the best receivers in the league this season. Stopping him is job one for the secondary.

Coming home: Rashied Davis, who was one of the Bears special teams leaders for six years, will face his former team for the first time. It's also the first time that Roy Williams and Mike Martz are visiting Detroit together since being reunited in Chicago. Williams had his best receiving season under Martz in Detroit.

Goin' streaking: The Lions have won eight games in a row, dating back to last season. Their last loss? To the Bears on Dec. 5 in Detroit.

History lesson: The Bears have an all-time record of 93-64-5 against the Lions, making them the team the Bears hold victories over Detroit than any other team in the NFL.

Injury report: The Bears will again be without Earl Bennett and Gabe Carimi, as well as Corey Wootton. The back-up defensive end broke his hand in practice last week. Davis, who was looking forward to playing the Bears, won't play because of a foot injury. Jason Fox and Eric Coleman will also miss the game.
