Nottingham Panthers coach Corey Neilson says his players' accountability will decide who keeps their place in the line-up this weekend.
Panthers now have one extra import than the permitted 10, so one will have to sit out each match.
Neilson, whose side face Braehead in the Challenge Cup this weekend, told BBC Radio Nottingham: "It could be injuries and a whole bunch of stuff.
"Part of it is accountability in terms of who is playing the best."
Panthers are in Braehead on Saturday for the first leg of their cup semi-final and the game also doubles up as an Elite League encounter.
The second leg is at the National Ice Centre on Sunday (1600 GMT).
Neilson was carrying an injury last weekend but says he would have played through the pain barrier in the 4-1 victory in Cardiff on Sunday, but decided to drop himself following a poor performance in defeat to the same opposition the night before.
He added: "I felt I didn't do a good enough job on Saturday, therefore I didn't play [on Sunday].
"It's a precedent that's going to be set early. It doesn't matter who you are, if you're not doing your job to the best of your ability then you're not going to play."
