CINCINNATI (AP) -Bengals defensive end Antwan Odom was taken off the field on a cart after injuring his left Achilles' tendon in the first quarter.

Odom, tied for the NFL sacks lead with eight, got hurt on Houston's 12-yard touchdown pass with 48 seconds left in the first quarter Sunday. The training staff felt the lower leg and immediately called for a cart to take Odom off the field.

The defensive lineman has been the key Cincinnati's improved pass rush. He also blocked a field goal attempt on Houston's first possession.
