Connor Barwin carted off with injury

HOUSTON -- Houston Texans defensive end Connor Barwin was carted off the field in Sunday's opener against Indianapolis with a dislocated right ankle.

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 and serves as a third-down end that factors big into the Texans' run defense schemes.
