Bears rookie Knox hurt

Chicago Bears rookie Johnny Knox injured an ankle while

returning a kickoff in the third quarter against the Minnesota

Vikings on Monday night and had to be taken off the field on a

cart.

Knox, a fifth-round draft pick from Abilene Christian who has

also played wide receiver, made a 31-yard return and was injured on

the tackle. He was able to get to his feet with assistance before

the cart was summoned and he was taken to the locker room.
