ATLANTA — Falcons coach Mike Smith says linebacker Lofa Tatupu will miss the season with a pectoral injury.

Smith said Tuesday tests revealed Tatupu will require season-ending surgery.

The Falcons report for training camp today. Akeem Dent, a third-round pick from Georgia in 2011, and veteran Mike Peterson, who was re-signed on Monday, will compete for the starting job at middle linebacker when camp opens Thursday.

Curtis Lofton, the team's leading tackler the last three years, signed with New Orleans. The 29-year-old Tatupu signed a two-year deal with the Falcons as a free agent. He did not play in 2011 following his release from the Seattle Seahawks before the season. Tatupu was a three-time Pro Bowl pick with Seattle.

Steelers

The Pittsburgh Steelers and coach Mike Tomlin have agreed to a new five-year contract that will keep him with the franchise through 2016.

Financial details of the deal, signed Tuesday, were not disclosed. Tomlin's previous contract ran through the 2013 season.

Team president Art Rooney II called Tomlin one of the best coaches in the NFL. The 40-year-old Tomlin is 55-25 in five seasons in Pittsburgh, winning three AFC North titles, two AFC championships and the 2009 Super Bowl.

The team made Tomlin a surprise selection to replace Bill Cowher following the 2006 season. Under Tomlin's guidance the Steelers have consistently been among the best teams in the league.
