Centre Nate Thompson also didn't practice Monday when the Ducks began preparations for their first-round playoff series against Winnipeg.

Frederik Andersen is expected to be the Ducks' starter against the Jets. Anaheim recalled Jason LaBarbera to be his backup.
Thompson incurred an upper-body injury during the Ducks' season-ending victory at Arizona last weekend.
