No criminal charges will be brought against a professional ice hockey player arrested on suspicion of manslaughter following the death of Adam Johnson.
The Nottingham Panthers player, 29, died after suffering a neck injury from a skate during a collision with Sheffield Steelers' Matt Petgrave on 28 October 2023.
The Crown Prosecution Service (CPS) said it worked with South Yorkshire Police to determine whether any criminal charges should be brought.
"We have concluded that there is not a realistic prospect of conviction for any criminal offence and so there will not be a prosecution," Michael Quinn, deputy chief crown prosecutor, said.
Mr Quinn added: "This was a shocking and deeply upsetting incident.
"The CPS and South Yorkshire Police have worked closely together to determine whether any criminal charges should be brought against the other ice hockey player involved.
"Our thoughts remain with the family and friends of Adam Johnson."
He said the police investigation had been "thorough" and the CPS had undertaken a "comprehensive review of all the evidence".
Mr Petgrave, who is Canadian, spent 17 months on bail after he was arrested in November 2023.
He was rebailed seven times by South Yorkshire Police as the investigation continued.
Mr Petgrave had denied the allegations and called the incident a "tragic accident".
