Green Bay, WI (Sports Network) - Aaron Rodgers passed for two touchdowns and Ryan Grant ran for two more, as the undefeated Green Bay Packers rolled to a bittersweet 46-16 victory over the Oakland Raiders.

Green Bay's 19th straight win -- the second longest streak in NFL history -- was suppressed when Greg Jennings went down with a knee injury in the third quarter. Jennings was tackled by a pair of Raiders defenders after making a catch along the right hash mark, and one fell directly on the back of the star wide receiver's left knee.

Jennings was visibly shaken after the incident and was carted to the locker room after a visit with team trainers on the sideline.

The injury cast a shadow over the NFC North-champion Packers becoming the second defending Super Bowl champion to start the following season 13-0.

Rodgers threw for 281 yards with an interception on 17-of-30 passing in less than three quarters, while Grant added 85 yards on 10 carries.

Carson Palmer was intercepted four times for the Raiders (7-6), who fell one game behind the AFC West-leading Broncos. Palmer threw a late touchdown pass and had 245 yards on 24-of-42 throws.
