Neal did not play Game 2 of the team's Eastern Conference Quarterfinal series on Friday in Pittsburgh after he sustained a lower-body injury during the second period of Game 1 against the New York Islanders.
According to the Penguins website, Neal "skated a few laps on the ice four roughly 10 minutes in warm-ups."
"With our injuries and lineup will not be a discussion point," coach Dan Bylsma said. "Obviously we had some people on the ice and some people off, and that will be the way it is for some practice days."
The Islanders won Game 2, 4-3, to tie the best-of-7 series 1-1. Game 3 is Sunday at noon (NBC).
Neal was injured during a power play when he was hit by an Islanders player along the boards. He played 8:09 over 10 shifts.
He was out from April 5-April 27 with an upper-body injury; he scored four points in his return for the regular-season finale against the Carolina Hurricanes before beginning the Stanley Cup Playoffs.
After scoring 40 goals in 80 games last season, he had 21 in 40 games this season.
