■ The N.F.L. is running out of stars. Last week J. J. Watt and Odell Beckham Jr. sustained season-ending injuries. This week claimed Green Bay Packers quarterback Aaron Rodgers, who is probably out for at least the regular season. Rodgers was driven into the turf at the end of a play against the Minnesota Vikings and left the field with a broken right collarbone. The Packers claim to be confident in Brett Hundley at quarterback, but he played poorly in relief of Rodgers.

■ Super Bowl hangovers are no fun. The Atlanta Falcons came out of their bye week hoping that the time off would erase the bad memories of a Week 4 loss to Buffalo. A 17-0 lead over the Miami Dolphins at halftime had things moving in the right direction, but a second-half collapse — a difficult subject for Atlanta fans after last season’s Super Bowl — resulted in a shocking 20-17 defeat. It was almost enough to make Jay Cutler seem happy. Almost.

■ Not every break can go the Kansas City Chiefs’ way. During their 5-0 start to the season, they continually got huge fourth-quarter defensive plays to seal their wins. On Sunday, they nearly picked off a Ben Roethlisberger pass, which would have gone a long way to securing a come-from-behind victory over the Pittsburgh Steelers. But the tipped ball ended up in the hands of Steelers receiver Antonio Brown, who raced into the end zone for a game-icing 51-yard touchdown.
