The Milan-Cortina Winter Olympics will take place from 6-22 February, with ice hockey matches split between the new Santagiulia Arena and the existing Milano Rho Arena.
The rink in Milan, approved by the IIHF, is shorter than the minimum requirement in the NHL, leading to suggestions there could be an increase in high-speed collisions.
During the test event, there was a short delay while a small hole in the ice had to be repaired on Friday before the other matches took place without incident.
IIHF president Luc Tardif said “the puck was sliding and not bumping” and believes “there is no reason that the NHL will not come”.
NHL commissioner Gary Bettman told reporters: “There are still challenges because the building is still under construction and the ice is new.
“We’ve been assured that, or we expect, that everything that needs to be done on a timely basis will get done.
“But, as you know, it’s not our event. We’re invited guests. We’ve offered to help and consult and advise as they feel they need and would be appropriate because we do have a little bit of expertise in that area.”
