Alex Brown retires as a Bear

Nine-year NFL veteran Alex Brown signed a one-day contract with the Chicago Bears and promptly retired from football on Wednesday.

Brown, who was not on a roster during the 2011 campaign, spent eight seasons in Chicago and recorded 43.5 career sacks with the Bears  the fourth highest total in franchise history.

Brown started 123 of 143 regular-season games played. He recorded 412 tackles, 59 tackles for losses, 45.5 sacks, five interceptions, 16 forced fumbles, 12 fumble recoveries during his career.

A locker room favorite during his tenure in Chicago, Brown was a major contributor for one of the NFL's top defensive clubs of the past decade. As a starting end on the 2006 Bears team that reached the Super Bowl, Brown recorded 47 tackles, six sacks and two interceptions. Brown's final pro season was a member of the New Orleans Saints in 2010.

The Bears will honor Brown before Thursday's preseason opener at Soldier Field against the Denver Broncos.
