The Green Bay Packers lost a lot more than just an important divisional game last night against the Chicago Bears. They lost their quarterback, Aaron Rodgers, who may miss at least a few games.

Seneca Wallace entered the game to replace Rodgers, but it just went downhill from there as the backup threw an interception on the first drive he commanded.

The wild events of the night started when Packers fans entered Lambeau Field with their favorite team sitting nicely in first place; the Bears were in third place but only a game behind Green Bay. Hours later, the Packers were suddenly in second place and the Bears entered an official three-way tie for first place in the NFC North.

Before the game was even over, the Packers were feeling the effects of playing without their star quarterback.

"Aaron's a huge part of our offense," coach Mike McCarthy said. "This is a thing that's been built over time with Aaron as the centerpiece. I don't think it's realistic to put anyone in there and expect him to perform (like Rodgers)."

Assuming Rodgers' injury is too serious to have him suit up next weekend, Wallace will get the start. Wallace is 6-15 in his NFL career with 27 touchdowns and 13 interceptions. The last time he started was in Week 7 of the 2011 season, according to ESPN Stats and Information.

Meanwhile, the Bears thrived with their backup quarterback, Josh McCown, who was filling in for the injured Jay Cutler. He took advantage of his opportunities and led his team to a 17-10 halftime lead. In the second half, the Packers managed to tack on 10 but the Bears stayed with them for the rest of the game and ended up with a 27-20 victory on the road.

"It'd be hard to find one better than this," McCown said after the game. "They're all special, but this is really neat because it means so much to our team."
