The Chicago Bears continue a four-game stretch of AFC West opponents as they travel to Oakland on Sunday for a Week 12 tilt against the division-leading Raiders.  The Bears will be playing in their first game without franchise quarterback Jay Cutler, who broke the thumb on his throwing hand in the team's Week 11 victory over San Diego.  Cutler underwent surgery earlier this week and is expected to be out at least the rest of the regular season.  Caleb Hanie will get his first NFL start.  Chicago has won five games in-a-row to sit in a two-way tie with Detroit for second in the NFC North division at 7-and-3.  Meanwhile, the Raiders are coming off a 27-21 win over Minnesota on Sunday to up their mark to 6-and-4 on the season.  Chicago has won both head-to-head matchups since the 2001 season.  The Bears beat the Raiders in Oakland, 17-6, in the team's last meeting during the 2007 season.
