All Blacks and Hurricanes hooker Dane Coles is set to return this Friday for his side's Super Rugby quarter-final clash with the Brumbies after he was sidelined for four months through ongoing concussion issues.
Coles is not the first high-profile All Black to suffer from the debilitating illness.
One-Test lock James Broadhurst was forced to retire earlier this year from the condition, with Chiefs and All Blacks midfielder Charlie Ngatai almost following suit before returning to the rugby field earlier this year.
The 30-year old Coles said Broadhurst was a major part of his recovery, although he wasn't too fond of one gift from his former team-mate following the confirmation of his illness.
"Yeah Broady brought a concussion book in the first week but I didn't want to read that! But I did speak to him because he's a pretty good mate and he was supportive."
The 49-Test hooker said he also received support from Charlie Ngatai after the Hurricanes' game with the Chiefs.
"It was good to see a guy like Charlie come back and he was really positive about it and gave me a few tips and advice."
"Maybe this has galvanised them, hearing each other's stories and knowing they are not alone," say the nurses behind the Facebook group, New Zealand, please hear our voice.
