The National Football League lost one of it's most dominating linebackers ever today as Brian Urlacher announced his retirement. In 13 seasons with the Chicago Bears, the former New Mexico Lobo quickly established himself as one of the game's most prolific tacklers. Urlacher ends his Bears career ranked first all-time in tackles, 8th in games played, 7th in sacks, and tied for 11th in interceptions. His next stop is Canton, Ohio and the Pro Football Hall of Fame. Here's a cool tribute video mix from The96Kai.
