Malkin rotated with center Carter Rowney between Scott Wilson and Patric Hornqvist. After watching the first few reps from center ice, he joined Pittsburgh's first power-play unit.
The Penguins are 3-1-0 in their four games without Malkin.
"I think they've done a great job," Malkin said. "I'm glad. 'Great job guys.' … But I want to play, for sure."
Before the injury, Malkin, who has not gone consecutive games without a point since failing to score in two straight on Nov. 16 and 18, had flourished with 10 goals and 21 points in his past 16 games. He is second on the Penguins, behind Sidney Crosby, with 22 goals and 54 points in 47 games.
His 1.15 points per game this season is his highest average since 2013-14, when he averaged 1.20 points in 60 games.
Malkin's injury forced him to miss the 2017 Honda NHL All-Star Game. In the lead-up to the event, he wasn't included on the list of the 100 Greatest NHL Players presented by Molson Canadian.
Malkin joked he didn't want to be reminded of his exclusion. He also paid respect to those who were included.
"I'm trying to forget," Malkin said. "I'm proud of what the team said and what Mario [Lemieux] said. I'm proud of my family and fans, and my friends. They support me and I did my best. … All 100 players are legends. They deserve to be on this list.
"Maybe I'll win a couple more trophies and a couple more Stanley Cups, and maybe next year in the NHL's 101st year, maybe … I'll be No. 101."
For now, Malkin is more focused on returning from his injury.
