Starting next season, not only the NHL will have a format of 3-on-3 overtime but also the Swiss league has decided to adopt the system for the regular season starting next year.

The challenge available to coaches has been set up in the NHL for this season and will now also come into use at the Spengler Cup. It allows coaches to intervene after a goal if they think it was an offside or the goalie has been interfered with. (lcu)
