(CBS) Running back Marion Barber and defensive tackle Amobi Okoye are the latest additions to the Bears, as both players agreed to contracts with the team Saturday.

Barber, who signed a two-year deal, will provide running back depth and could unseat Chester Taylor as Matt Forte’s backup. Barber gives the Bears another receiving weapon out of the backfield as he has 174 receptions in his six-year career, good for 1,280 yards and six touchdowns. His 47 rushing touchdowns over the last six years rank sixth in the NFL.

Okoye also has a good chance to contribute immediately. He started 58 of 62 games over the last four seasons with the Houston Texans, but was cut when the team switched to a 3-4 defense. Okoye only signed a one-year deal with the Bears, but he gives the team some toughness inside. Okoye led the Texans’ defensive line last year with 44 tackles and added three sacks.
