Hornqvist has not played since leaving warmups prior to Game 2 of the series on May 15 because of an upper-body injury. Schultz hasn't played since sustaining an upper-body injury on a hit into the end boards by Senators forward Mike Hoffman in the first period of Game 2.

Each player has been skating on his own on and off since then. Hornqvist, who has seven points (four goals, three assists) in 13 Stanley Cup Playoff games this season, joined the Penguins on the ice for their optional morning skate Thursday but did not speak to the media afterward.
Schultz, who has eight points (two goals, six assists) in 14 playoff games, did not skate Thursday.
Right wing Conor Sheary, a healthy scratch the past two games, came off the ice at the end of the morning skate with the other players who are expected to play Thursday. Right wing Josh Archibald stayed on for extra work, so it appears Sheary might play in Archibald's place if Hornqvist is unable to play.
"[Hornqvist's] a game-time decision and there's a few guys that are game-time decisions," Sheary said. "So I think we all have to be ready to play tonight."
Defenseman Chad Ruhwedel also skated wearing a yellow non-contact jersey. It was his first time on the ice with the Penguins since sustaining a concussion on a hit from Senators right wing Bobby Ryan in Game 4 on Friday.
Right wing Tom Kuhnhackl (lower body) skated on his own in a warmup suit prior to the morning skate.
