Texans DE Barwin leaves with leg injury

Houston Texans defensive end Connor Barwin was carted off the field in Sunday's opener against Indianapolis with a right leg injury.

Barwin went down in the first quarter when Houston defensive tackle Antonio Smith accidentally slid into him while they were chasing Joseph Addai on a running play. Barwin ripped off his helmet in obvious pain, and Houston coach Gary Kubiak joined medical staff on the field.

Barwin was lifted onto a cart, and several Texans surrounded Barwin before the cart left the field.

Barwin backs up All-Pro defensive end Mario Williams.
