Crosby did not participate in an optional skate Saturday morning and was unavailable for comment, but he went through his usual game-day routine, including playing soccer in the hall.
Sheary said he passed a baseline test Friday. Asked if Crosby had done the same, coach Mike Sullivan said yes.
"Sid will be a game-time decision," Sullivan said. "He has had a number of really positive days. His status still hasn't changed to this point, but he'll be a game-time decision. Conor's the same."

The NHL Concussion Evaluation and Management Protocol states: "There is no mandatory period of time that a Player must be withheld from play following a concussion, as the return to play decision is based on the individual circumstances of that player."
A player must satisfy three criteria to return to play: 1. Completely recover from concussion-related symptoms at rest. 2. Have no emergence of concussion-related symptoms at exertion levels required for competitive play. 3. Be judged by the Club's Physician to have returned to his neurocognitive baseline following an evaluation by the Club consulting neuropsychologist.
"The Club Physician remains solely responsible for making return to play decisions based on these parameters," according to the protocol.
Crosby and Sheary each sustained a concussion in Pittsburgh's 3-2 overtime loss in Game 3 on Monday and sat out a 3-2 win in Game 4 on Wednesday. Crosby skated for three straight days and Sheary for at least two days. Each took part in a full-contact practice Friday.
Sheary took part in the morning skate and said he was monitoring himself for symptoms.
"We'll see how the day goes and see how I feel and go from there," Sheary said. "Obviously with this injury, you've got to kind of wait it out and see how you feel."
Asked if the 3-1 series lead factored into the Penguins' decision-making on the players' returns, Sullivan said: "I think that we trust our doctors and the process that they go through, and when they tell us that these guys are healthy and are cleared to play, then that's all we need to know.
