Marshall, missing his second game in a row Sunday because of a right hamstring injury, was limited in practice this week but had said he expected to play. Crowder sat out practice all week because of a knee injury.
Miami reserve cornerback Al Harris (hamstring) was also inactive.
Linebacker Karlos Dansby and defensive end Phillip Merling were active for Miami. Dansby has been slowed by a toe injury, while Merling rejoined the roster Tuesday, less than four months after an Achilles' tendon injury that was feared to be season-ending.
