Veteran free safety Mike Brown was credited with 17 tackles by coaches after they finished reviewing game tape.
That's a career-high for Brown, whose previous high was 13 at Washington in the 2005 season opener.
It marks the second straight game a safety led the team in tackles, which means plays are finishing up downfield.
Charles Tillman was second with 11 tackles and Lance Briggs and Brian Urlacher were each credited with nine.
Defensive tackle Tommie Harris made one and now has two for the season.
Brown leads the team for the year with 26, followed by Tillman at 24 and the Pro Bowl linebackers at 23 apiece.
