The Penguins practiced with all their regular players for the first time this season Wednesday.
Forwards Danton Heinen and Zach Aston-Reese, and backup goalie Casey DeSmith practiced after being removed from NHL COVID-19 protocol. The Penguins have no players in the protocol.
The three likely won't play against the Ottawa Senators on Thursday (7 p.m. ET; ATTSN-PT, TSN5, RDS, ESPN+, NHL LIVE), coach Mike Sullivan said.
"There's competition for every position on our team," Sullivan said. "Everybody, when they come out of this COVID protocol stuff, they all react differently. So we have a lot of interaction with each player, and the players' feedback themselves is a big part of it. When we do insert players into the lineup, we're trying to put them into position to be successful."
Forward Drew O'Connor is the only injured player; he is week to week with an upper-body injury. If healthy, O'Connor would likely be assigned to the taxi squad or Wilkes-Barre/Scranton of the American Hockey League.
The Penguins began the season without centers Sidney Crosby and Evgeni Malkin. In addition to injuries to other key players, including forwards Jake Guentzel, Bryan Rust and Jason Zucker, Pittsburgh has had a bulk of its lineup enter COVID protocol.
Forward Jeff Carter has entered protocol twice. Crosby, Guentzel and Rust, defensemen Kris Letang and Brian Dumoulin, and goalie Tristan Jarry each was also in protocol earlier this season.-- Wes Crosby
