■ The Falcons’ Matt Ryan became the first quarterback since Green Bay’s Bart Starr in 1967 to win a game despite throwing five interceptions with no touchdowns, according to STATS LLC.
■ Phil Dawson of the Browns increased the longest active field goal streak to 25. He’s 19 of 19 this year.
■ Drew Brees of the Saints has won his last seven starts against the Raiders, with 16 touchdown passes and no interceptions.
■ Trent Richardson fell 5 yards shy of becoming the first Browns rookie with three straight 100-yard rushing games.
■ Late in Detroit’s loss, Lions receivers coach Shawn Jefferson was seen screaming at offensive coordinator Scott Linehan on the sideline.
■ After 26 consecutive holds, the Broncos’ defense gave up a conversion on third down. It was the longest such streak in the NFL in 10 years.
■ In their last six losses, the Panthers have held a fourth-quarter lead in five of them.
■ Five of the Browns’ eight losses have been by a touchdown or less.
■ The Cowboys won for the first time in six games when Tony Romo is sacked at least five times.
■ The Chiefs have lost seven straight games in one season for the first time since Oct. 5-Nov. 23, 2008. Thousands of fans at Arrowhead Stadium were dressed in black to convey their displeasure with management. An airplane towed a banner — paid for by fans — asking for general manager Scott Pioli to be fired. Some fans handed out fliers pleading for the same result.
When, where: 8:30 p.m., at Candlestick Park.
TV, radio: ESPN, WEEI (93.7).
Line: 49ers by 6½.
Last meeting: 49ers won, 10-6, in 2009.
Of note: We know Jay Cutler is out for Chicago. Alex Smith will be a game-day call for the 49ers. Having two backup quarterbacks in there would give an even greater advantage to the defenses — they both entered the weekend ranked in the top five in total yardage and points allowed. Though the teams have no recent history, they do have three common opponents so far this year. In going 2-0-1 against the Packers, Lions, and Rams, San Francisco had more than 340 total yards in each game. Against the same trio of teams, Chicago is 2-1 without reaching 300 total yards once.
