The Pens held practice on Thursday afternoon after a 5-1 setback in Game 3 against the Ottawa Senators that has them in a 2-1 series deficit in the Eastern Conference Final.
Forwards Bryan Rust and Patric Hornqvist skated prior to practice in warmups. Both players have upper-body injuries and are unlikely to play in Game 4 Friday night at Canadian Tire Centre.
"They're still day-to-day," head coach Mike Sullivan said. "We're hopeful (they can play). We'll see what happens, but obviously they didn't skate with the team. They're probably not probable."
Defenseman Justin Schultz (upper-body) did not skate Thursday as part of his recovery plan. But Sullivan noted that Schultz isn't necessarily behind Rust and Hornqvist in his recovery.
"It was just part of his process," Sullivan said.
The only other player absent from practice was forward Tom Kuhnhackl, who is day-to-day with a lower-body injury.
*Defenseman Mark Streit made his Pens' postseason debut in Game 3 as the team dressed seven defensemen. He logged 15:30 minutes of ice time, his first game action since April 9.
"The first period was a little rough. It's a quick game so you need a little bit of time (to adjust)," Streit said. "After I felt pretty good.
"It was a tough game to jump in, but definitely great to play."
Streit worked on the Pens' top power-play unit and picked up an assist on the team's lone goal of the game.
During practice on Thursday he worked with the second unit, while Trevor Daley took the midpoint position with the first power-play group.
