NASHVILLE - The health of Nashville defenceman Ryan Ellis is in question after he couldn't finish Game 5, and the Predators are offering no clues at all for Game 6 on Sunday night.

Ellis did not skate Saturday, though several Predators did not take the ice in an optional practice. Ellis missed most of the second and third periods in Thursday night's 6-0 loss in the Stanley Cup Final.

Roman Josi says his defensive partner obviously is a huge part of the Predators' defence. Ellis had a seven-game points streak this post-season.

The Penguins are a win away from their second straight Stanley Cup and fifth overall. They skated in Pittsburgh before flying to Nashville. Center Nick Bonino, who has missed three straight games with an injured left foot, did not practice for the Pens.
