Puljujarvi was with Ryan Nugent-Hopkins' line at practice on Friday.
"I think most of our decisions are based on eyeball evidence," said Head Coach Todd McLellan. "It's watching the games, and the more we watch him the more he's involved in the offence. He's creating as many chances or opportunities for himself or for his teammates as anyone else on the team. That's been a real good thing. He looks and feels more confident, I believe - stronger, night in and night out. So why not give him more ice time and give him more opportunity? If he makes good on it, we'll slowly work him in further and further up the lineup."
