The Chicago Bears have signed running back Marion Barber, wide receiver Roy Williams and defensive tackle Amobi Okoye. Barber, who inked a two-year deal, is the third former Cowboy to join the Bears for this upcoming season. Williams inked a one-year contract Friday and fellow wideout Sam Hurd is also on his way to Chicago. Barber played in 13 games for Dallas last year, rushing for a career-low 374 yards and four touchdowns. Okoye, the 10th overall selection by the Houston Texans in the 2007 draft, started 58 of 62 games over four years with Houston. Last season, he recorded four sacks and led all Houston defensive lineman with 44 tackles.

The Bears also locked down veteran defensive tackle Anthony Adams for two more years and added another defensive lineman in former first-round draft pick Vernon Gholston. They also inked their first round pick from Wisconsin, offensive lineman Gabe Carimi and second round defensive lineman, Stephen Paea, who came from Oregon State.
