CHICAGO -- The Bears have placed Dusty Dvoracek on the waived/injured list after ruling him out for the season last week because of a torn ACL in his right knee.
Dvoracek had surgery Friday after going down in a preseason game against the New York Giants.
If he clears waivers, Dvoracek reverts to injured reserve. He could also work out an injury settlement with the Bears.
This is the fourth season-ending injury in as many years for Dvoracek, who has appeared in just 13 games since Chicago drafted him in 2006.
He went on IR as a rookie with a preseason foot injury, tore his left ACL in the 2007 season opener, and started 12 games last year before going out for the season with a torn biceps.
