Wish Brian Urlacher all the best in his post-NFL life. His love of the game was always on display. Seemed like a man born to play football

Mike Singletary (10) and Walter Payton (9) are the only Bears to make more Pro Bowls than Brian Urlacher (8).

Congratulations @BUrlacher54 on your retirement. You were one of the fiercest players I ever stood across the line of scrimmage from.

You were who we thought you were. Congrats. RT @BUrlacher54: It was an honor to play my entire career for the @ChicagoBears.

Brian Urlacher retires. He's 1 of 4 players in NFL history with 40 sacks and 20 interceptions (sacks became official in 1982).

Brian Urlacher…20+ picks, 40+ sacks and we'll see him in a yellow jacket instead of another jersey. #Man'sGame.
