Context: The Bears faced off on Monday night against the San Francisco 49ers in a battle of backup quarterbacks between Jason Campbell and Colin Kaepernick after Jay Cutler and Alex Smith were lost for the game due to concussions. With Campbell and Kaepernick making their first starts of the 2012 season, the game marked the first tine two quarterbacks made their first starts of the season on Monday Night Football in a non-strike season (besides Week 1) since 1979 between Los Angeles Rams and Atlanta Falcons quarterbacks Vince Ferragamo and June Jones in Week 12. In Kaepernick's first career start, he completed 16 of 23 passes for 243 yards with two touchdowns and a 133.1 rating, while Campbell struggled, completing 14 of 22 passes for 107 yards with one touchdown, two interceptions and a 52.7 passer rating. Campbell was also sacked six times, including 5.5 times by Aldon Smith, the most by an individual on Chicago's opposing team. After David Akers made a 32-yard field goal, and the Bears went three-and-out, Kaepernick completed a 57-yard touchdown pass to Kyle Williams to give the 49ers a 10-0 lead in the first quarter. In the second quarter, 49ers running back Kendall Hunter scored on a 14-yard run, followed by Akers' 37-yard field goal. In the second half, the 49ers continued their dominance, with Kaepernick hitting Michael Crabtree on a 10-yard touchdown pass, which was countered by Campbell hitting Brandon Marshall on a 13-yard pass. In the final quarter, Akers hit a 32-yard field goal, and San Francisco recorded a safety when Campbell fumbled while getting sacked, with the ball being recovered by Bears offensive lineman Chilo Rachal in the endzone, making the final score 32-7. The loss dropped Chicago to a 7-3 record, tying them with the Packers for the division lead. The loss was the eighth consecutive loss at Candlestick Park since 1985.
