Former NHL star Johnson, 29, suffered a gash to his throat in the freak accident, according to witnesses.
The game between his new team the Nottingham Panthers and the Sheffield Steelers had to be abandoned.

Around 8,000 fans are believed to have witnessed the horror collision between the two players at Utilita Arena Sheffield.

The team said: "The Nottingham Panthers are truly devastated to announce that Adam Johnson has tragically passed away following a freak accident at the game in Sheffield last night.
