As Nelson gained the zone, he sustained a hit to the head by Scandella’s left shoulder.
The two-game ban means Scandella will forfeit $11,021.50 US.
It was also in the same game that Wild defenceman Keith Ballard suffered multiple facial fractures and a concussion after getting hit along the boards by Islanders winger Matt Martin
The Wild announced Wednesday that Ballard will be out indefinitely.
