The Lions have confirmed that linebacker Jordon Dizon, who seriously injured his knee against the Steelers on Sunday, is out for the season. Dizon was placed on injured reserve today, officially bringing his 2010 campaign to a close before it really even got started.

To add some depth at linebacker and fill Dizon's spot on the roster, the Lions brought back Lee Campbell, who was released on July 31. Campbell was picked up in June off waivers after the Giants let him go, but he was released at the start of training camp to make room on the roster for Isaiah Ekejiuba. With a need at linebacker popping up because of Dizon's injury, the Lions decided to simply bring back a familiar face.

Campbell is in his first year in the league as an undrafted player from Minnesota.
