The coach of the US men's hockey team Tony Granato was so mad over Saturday's defeat he refused to shake hands with Oleg Znarok, the coach of the Russian team.

Team USA played Team OAR (Olympic Athletes for Russia) in the group stage of the Olympic hockey tournament at Gangneung Hockey Centre in South Korea, losing 4-0.

NBC analyst Pierre McGuire said during his broadcast that Granato was 'furious' when that Team OAR tried to score some last minute goals when they had already won the game, according to the New York Post.

When it came time for the two coaches to meet and shake hands at the end of the bout, Granato refused.

With only seconds left in Saturday's game, the Russian coach pulled a power play and sent 34-year-old Ilya Kovalchuk on the ice. The left winger scored two backbreaking goals less than 33 seconds apart at the end of the second period and start of the third.

During a post-game interview, Granato was asked if he was upset that Znarok pulled the last-second move. 'Yes,' the US coach said sternly, the Washington Post reports.

He later added: ‘I thought we played well enough to deserve better than a 4-0 game. I was really happy with the effort and the confidence that we gained in knowing that we could play with them. We just didn’t get the results.’

Team USA will now play in the qualification round on Tuesday, while Russia will move on directly to the quarterfinals.
