FOOTBALL

As part of the celebration of its 100th season, the NFL will have the Green Bay Packers play at the Chicago Bears in the Thursday night kickoff game Sept. 5.

Traditionally the Super Bowl champion is the home team for the prime-time opener, but the league wants to salute historic rivalries. No rivalry fits better than Chicago vs. Green Bay. The teams have met 200 times since 1921, when the Bears were the Chicago Staleys. Green Bay leads the series 97-95-6 in the regular season, with the clubs splitting two postseason meetings.

Staging the game at Soldier Field – even if it is a modernized version of the stadium – adds to the theme.

New England instead will open at home in the prime-time game Sunday night, Sept. 8. The opponent has not been determined.

AUTO RACING

NASCAR: The qualifying procedures were tweaked to avoid a repeat of the session two weeks ago in which all 12 drivers in the final round failed to log an official lap.

Scott Miller, the senior vice president of competition, accused drivers of “making a mockery out of the qualifying process” when they all idled on pit road until the final second to attempt their qualifying lap. But the drivers all blew the timing, none completed a lap before the clock ran out, and fans booed the shenanigans. So beginning Friday, all cars must post a lap time or start at the rear of the field. Once a car leaves its pit stall, it cannot stop on pit road.
