Gold is coming off a severe knee injury, but could be a major addition to the defense. A Pro Bowler on special teams in 2001, Gold also started for two seasons at weakside linebacker before suffering an ACL injury that cut his 2003 campaign short.
The Bears signed offensive lineman Michael Keathley to a one-year deal on Thursday. He is expected to compete with Terrence Metcalf and Josh Warner for the second string center spot behind starter Olin Kreutz.
Kreutz has been excused from the weekend workouts because of personal reasons. Mike Green will also not participate, as the team doesn't want him to re-aggravate a groin injury that forced him to miss 6 games last season.
