The Chicago Bears' defensive-line depth took another hit Monday when veteran end Turk McBride was lost for the season to a ruptured Achilles tendon but the injury news could have been worse.

The Bears got a scare when Jermon Bushrod their biggest free-agency addition left practice early with what turned out to be only a mild calf strain.

Although his status is day-to-day he was later seen entering the dining room wearing a walking boot.

"It's nothing crazy" said Bushrod calling the boot precautionary.

Bushrod the two-time Pro Bowl left tackle signed to help revamp the offensive line came out after one brief team period with a bag of ice taped to the back of his right leg. He was replaced for the next period by Jonathan Scott.

McBride will be missed on a defensive line that earlier lost end Sedrick Ellis who announced his retirement. Former Falcons defensive end Jamaal Anderson was signed to replace Ellis.
