Schneider was knocked unconscious after a skirmish with the Canterbury Red Devils in the second leg of a double-header in Christchurch.
He had been expecting ''some pushing'' but alleges he received a punch to the face.
''The whistle was a bit late, there was a loose puck and I just tried to get lucky and get it in,'' he said.
Schneider said the alleged punch connected with his jaw. He was taken to hospital in Christchurch that night, and his X-rays came back clear.
A recovering Schneider yesterday said, ''We do play a dangerous game but that's still uncalled for.''
New Zealand Ice Hockey Federation president Grant Hay said because the referee had not filed his report, he was unable to confirm details of the incident.
Hay had been told Canterbury captain Hayden Argyle was given a penalty for excessive roughness, which could lead to a two-game suspension and disciplinary tribunal.
But Hay said he could not confirm Argyle was responsible for the alleged punch Schneider received.
Hay had seen footage of the incident and, although it was not clear who had done what, ''incidents of this nature are not tolerated''.
''I consider ice hockey the safest contact sport to play based on our study of injury rates supplied by ACC.
''You have more than three times the chance of being injured if you own a skateboard than if you play ice hockey.''
Red Devils manager Graham Tappin said no-one from his team could comment on the incident because of the possibility of a disciplinary review, which the team would fully support.
Stampede captain Bert Haines said the incident happened after Argyle had broken his stick on Schneider.
The incident happened with less than 20 seconds left in the second period with the Devils leading 3-2, after the Stampede had earlier taken a 2-0 lead.
The Devils went on to win the game 4-2, the same score as on the previous night.
The Stampede has a bye this weekend, which gives Schneider time to rest up and see if he is well enough to play next week's first home games of the season against the Dunedin Thunder.
