Kaepernick earned the offensive honor after throwing a career-high four touchdown passes in the 49ers' 41-34 win at New England. He threw for 216 yards overall and added 28 yards rushing as San Francisco snapped the Patriots' 20-game home winning streak in the month of December.
Carr received defensive honors after intercepting Ben Roethlisberger's pass on the second play of overtime in the Cowboys' 27-24 triumph over the Pittsburgh Steelers. The pick set up Dan Bailey's game-winning field goal. Carr also tallied four tackles and three passes defensed.
The special teams award went to Walsh, who converted all five of his field- goal attempts, including three from 50 yards or longer, in the Vikings' 36-22 victory against the St. Louis Rams.
