Injuries to two key players blighted Sheffield Steelers' 8-2 mauling of Dundee Stars.
Zack Fitzgerald suffered a possible concussion and Mathieu Roy was again out of sorts as their team strolled past the Scots at iceSheffield on Wednesday night.
Coach Paul Thompson said d-man Fitzgerald took a "shot on the jaw" the effects of which will now be closely monitored.
With defensive cover at a minimum, it's certainly not what the team needs.
Winger Roy will have a scan on Friday to look again at an undisclosed problem which has plagued him all season long.
"It is very frustrating for him and us not moving forward with what his injury is or what is causing it" said the coach.
It was a deep seated issue which required more investigation, he said.
The player will have a scan on Friday.
Steelers play Manchester Storm at home on Saturday in a Challenge Cup group game.
Steelers have already qualified, so can at least rest the injured imports.
