Upon the Referee's signal
prior to the start of a period and following
any stoppage of play, the visiting team shall promptly place a lineup on the
ice, ready for play and no substitution shall be made from that time until
play has been resumed. The home team may then make any desired substitution
which does not result in the delay of the game.
If there is any undue delay by either team in changing lines, the
Referee shall order the offending team or teams to take
their positions immediately and not permit line changes.
(Note) When a substitution has
been made under the above rule, no additional substitution may be made
until play commences except when any penalty is imposed.
