Quinn, 20, was recalled Thursday and joined the lineup in place of Kyle Okposo, who is considered week to week. He played on the top power-play unit and scored his first NHL goal on a shot off the crossbar.
"At least Jack was in the game and showed us what Jack can do," Granato said. "Nice to see that. Obviously, injuries are a part of the game and it's unfortunate."
Anderson confirmed his upper-body injury occurred when Sharks forward Tomas Hertl made contact with him while scoring a goal in San Jose on Nov. 2. The 40-year-old had posted a .921 save percentage while starting six of Buffalo's first nine games.
"It's been a lot of long days here, going through treatment, the off-ice stuff, so just getting out there with the guys and realize that hockey is fun and puts a smile on your face when you're out there having fun with them, it was good," Anderson said. "It was an eye-opener. Haven't been on the ice for a while so rhythm and timing, conditioning, etc., that's all coming into play here."
Anderson estimated it will take five to seven practices to regain his conditioning and rhythm in goal.
"A lot of it right now is seeing pucks, getting the rhythm back," he said. "It's a lot different when you're seeing coaches flip pucks at you, going through some movement drills versus full-on, full speed, odd-man rushes, guys coming to the slot with the puck. So, there'll be some time to work through that. I want to make sure I'm comfortable in that situation before I say I'm ready to go."
Granato confirmed the net will be Anderson's when he is ready to return. The Sabres currently have a goaltending tandem of Aaron Dell and Michael Houser with Ukko-Pekka Luukkonen (lower body) week to week and Dustin Tokarski out indefinitely due to lingering symptoms of COVID-19. Malcolm Subban is expected to miss the rest of the season after having surgery to repair an upper-body injury.
"He's such a pro and a veteran," Granato said. "He knows what he needs. He knows how he feels with issue he's dealing with and he knows what it's going to take to get back to the level of his personal standard. It is incredible when you see him out on the ice because he has a presence in the net. He looks like a slight guy walking around here, inconspicuous. But when he puts that gear on and how he stands and how he holds posture, he just has a presence in the net. You see he's been a number one goalie in the NHL. That's really nice to see, that he's back doing what he wants to do.
"… If he's ready to go, he's earned that net and he'll be back in that net."
