Kruger finished the opening 20 minutes taking several shifts after the hit and came out on the bench for the second period but could not continue.
"He was on the bench in the second and had a couple times I called (for him). He didn't end up getting out there," coach Joel Quenneville said after the game. "Kruger is doing OK now. We'll see (Wednesday). We'll have a better idea on how he's doing. Tough hit, high hit, in tough area. He was in a tough spot."
Engelland was not called for an infraction while Hawks defenseman John Scott immediately jumped him and was given an instigator along with a 10-minute misconduct penalty. Engelland can still face supplementary discipline by the league despite the no call on the ice.
"It was a full body check," Penguins coach Dan Bylsma said.
Kruger played 6:04 before his night ended.
