NOTTINGHAM, England -- A makeshift shrine for Adam Johnson keeps growing outside the arena where the Nottingham Panthers play hockey.

Fans have left flowers, wreaths, jerseys, team scarves and handwritten notes to honor the American who died after an opposing player's skate cut his neck during a game last month in Sheffield. Johnson was 29.

"We're not just hockey fans -- we're a hockey family," Panthers fan Margaret Cartwright said Saturday.

The death of the former Pittsburgh Penguins player has not only forced the sport to reexamine safety regulations but also sparked a criminal investigation locally that led to an arrest of a man on suspicion of manslaughter.

The Panthers haven't played since that Oct. 28 game and will take the ice Saturday at Motorpoint Arena against the Manchester Storm in a memorial game "to celebrate the life of Adam and the remarkable person he was," the team said.

The game, which will be broadcast free on YouTube, does not count in the Elite Ice Hockey League standings. Instead, it's meant to bring players and fans together as they try to move forward.

A tribute to Johnson is planned before the opening faceoff and the 10,000 fans at the sold-out venue will be asked to rise in the 47th minute -- Johnson wore jersey No. 47 -- for a minute of applause.

A postmortem examination confirmed Johnson died as a result of a neck injury. Police made an arrest Tuesday and the person was released on bail a day later. South Yorkshire Police did not identify the suspect or provide an age.

Matt Petgrave, a defenseman for the Sheffield Steelers, was the other player involved in the incident. Johnson had skated with the puck across the blue line -- into Sheffield's defensive zone -- when Petgrave collided with another Panthers player. Petgrave's left skate kicked up as he began to fall and the blade hit Johnson in the neck.

Neither the Steelers nor the league has provided an update on Petgrave's roster status. His agent declined to comment when reached by The Associated Press this week.

"Everybody's dealing with it in their own way, some are being negative. The majority of us are trying to be positive," Cartwright said. "It was just a really, really unfortunate accident. The poor guy that caused it has got to live with that for the rest of life. I think that should be punishment enough. Nobody would do that deliberately -- nobody. It's just how it happened, in a split second something went wrong and unfortunately, we lost poor Adam."

The Minnesota native was in his first season at Nottingham -- a central England city known as home to Robin Hood -- after stints in Germany and a handful of games for the Penguins in the 2018-19 and 2019-20 seasons. He was living in Nottingham with his American girlfriend.

The English Ice Hockey Association, which governs the sport below the Elite League, reacted to Johnson's death by requiring all players in England to wear neck guards from the start of 2024.

The game in Sheffield was part of the league's Challenge Cup -- like soccer's FA Cup tournament in Britain -- but the Panthers have since withdrawn from that competition. They will resume their season against the Belfast Giants on Nov. 26.
