"It was good," Murray said. "Today was a skills day, so it was a little bit different than our usual practices. Still a lot of work for the goalies, which is good, and it's good to be back out there with everybody."
Penguins coach Mike Sullivan did not rule out Murray playing against the New York Islanders at Barclays Center on Tuesday (7 p.m. ET; TVAS, SN, MSG+, ATTSN-PT, NHL.TV).
"It's a big step for him," Sullivan said. "We'll see how he responds to today's practice, but he certainly looked pretty good out there today."
Murray, 23, has missed nine games since taking a shot to his mask from defenseman Olli Maatta during practice. He said his conditioning has held up well during his absence.
"I've been skating on my own for a few days now," Murray said. "It kind of slowly comes back to you."
Pittsburgh is 5-3-1 in his absence. The Penguins (41-26-5) are in second place in the Metropolitan Division, two points behind the Washington Capitals and six points ahead of the Philadelphia Flyers.
After winning the Stanley Cup in each of his first two NHL seasons, Murray is 23-13-2 with a 2.82 goals-against average and .909 save percentage in 41 games (37 starts) this season. He won nine of his past 11 games (9-1-1) before the injury.
Murray had one previous concussion, which forced him to miss the first two games of the Eastern Conference First Round against the Rangers in the 2016 Stanley Cup Playoffs. He returned to make 16 saves on 17 shots in Game 3 before finishing the playoffs 9-2-1 with a 2.00 goals-against average and .930 save percentage.
