DANA POINT, Calif. — The Super Bowl champion Steelers will open the 2009 NFL season in Pittsburgh on Sept. 10 against the Tennessee Titans.

In announcing the opening weekend's nationally televised games, the league also said the Chicago Bears will play at Green Bay in the first Sunday night game. Both the Titans-Steelers and Bears-Packers games will be on NBC.

The Monday night doubleheader on ESPN on Sept. 14 will feature Buffalo, with Terrell Owens, at New England, with, the Patriots hope, a returning Tom Brady. That game will be followed by San Diego at Oakland.

No changes were made in the traditional Thanksgiving afternoon games, which again will be hosted by Detroit and Dallas.

The Lions go back to meeting the Packers that day, a matchup that lasted several decades on the holiday, but only happens sporadically nowadays. The Raiders will be at the Cowboys following that, and the NFL Network night game will feature the New York Giants at Denver.

The Cowboys could not open their new stadium on the first weekend of the regular season because baseball's Texas Rangers are at home in their nearby ballpark. Cowboys vice president Stephen Jones indicated his team would be at home in Week 2 and a prime-time game was likely.
