DAVIE, Fla. (AP) — Miami Dolphins Pro Bowl tackle Jake Long is back at practice on a limited basis.

Long, nursing a left knee injury, was involved in some of Wednesday's workout. Linebacker Channing Crowder, who has been sidelined since Aug. 17 because of a groin injury, jogged on the side.

The Dolphins open the season Sunday at Buffalo.
