The San Francisco 49ers moved further clear at the top of the NFC West with a comprehensive 32-7 victory over the Chicago Bears on Monday.
Back-up quarterback Colin Kaepernick filled in admirably for the injured Alex Smith as the 49ers picked up their seventh win of the NFL campaign in front of a parochial home crowd at Candlestick Park.
The victory moves the 49ers one-and-a-half games clear of the Seattle Seahawks at the top of their division, while the Bears fall behind the Green Bay Packers in the NFC North.
Kaepernick impressed in his first career start, passing for 243 yards and two touchdowns in the rout.
David Akers opened the scoring for the 49ers with a field goal, before Kaepernick hit Vernon Davis with a three-yard pass to make it 10-0 at quarter-time.
Kendall Hunter ran in another touchdown for the 49ers early in the second, before Akers nailed a 37-yard field goal late in the half to ensure the home side led by 20 (20-0) at half-time.
The game was as good as over when Michael Crabtree caught Kaepernick's 10-yard pass at the start of the third term, although the Bears did hit back through Brandon Marshall.
Quarterback Jason Campbell hit Marshall with a 13-year pass for the Bears' first score of the match, but that was as good as it got for the visiting side.
Akers nailed his third field goal of the match at the start of the final term to make it 30-7 and the Bears added another two points shortly after through a safety.
Campbell, starting for the injured Jay Cutler, finished with 107 yards, but was sacked five times and threw two interceptions in his first start of the season.
