There is mutual interest between free-agent linebacker Lofa Tatupu and the Bears, according to a league source. Tatupu, who was released by the Seahawks over the weekend, has also been linked to the Raiders and Redskins. He has a strong connection to the Bears. Chicago assistant general manager Tim Ruskell drafted Tatupu out of USC in 2005 when Ruskell was the general manager of the Seahawks.
