Detroit Lions linebacker Jordon Dizon suffered a knee injury during Saturday's preseason game against the Pittsburgh Steelers and will be lost for the season.
Lions coach Jim Schwartz called the injury "serious,'' but did not confirm that it's a season-ending injury. Dizon, however, told several people after the game that he wouldn't be returning this year.
The injury is a blow to a position that already was lacking depth. Dizon was Detroit's No. 2 middle linebacker -- he started on Saturday for the injured DeAndre Levy -- and he was also a backup in the nickel defense.
Schwartz said after the game that if Dizon is lost for the year, the team will make a personnel move to replace him.
