Sheary required stitches for a split upper lip caused when he collided with Hornqvist on Monday and was hopeful he could play Saturday.
"I don't want to put myself in the clear yet," Sheary said. "I hope I have another good day today but I've been surprised with yesterday and today that I've been pretty much symptom-free. … As long as today goes well I think I'll be a game-time [decision] tomorrow."
Following line rushes, Crosby participated in full-contact drills with no apparent limitations. In eight games during the Stanley Cup Playoffs, Crosby has 11 points (four goals, seven assists).
Crosby missed the first six games of the regular season because of a concussion sustained during a preseason practice. He returned and led the NHL with 44 goals. His 89 points were tied with Chicago Blackhawks forward Patrick Kane for second, 11 points behind Edmonton Oilers forward Connor McDavid (100).
Crosby also missed 101 games during the 2010-11 and 2011-12 seasons, as well as the 2011 Stanley Cup Playoffs, because of a concussion and a neck injury.
"It was good. It was fun [to see Crosby practice]," goalie Marc-Andre Fleury said Friday. "I think the most important thing is his health. To have him out there cracking a few smiles and having fun playing hockey, it was fun to see."
