Afeaki had been dealing with a level of uncertainty almost as frustrating as the months spent beset by symptoms. He was always intending on a return to the field - one head knock should hardly undo a life's work - but the green light never arrived.
It did come agonisingly close, though, with Afeaki approaching full fitness a couple of weeks ago, before another visit with specialists and tests revealed the decisive news.
"A year of symptoms and the whole time I was doing everything right and trying to return to play - it was a bloody tough year," he said. "As soon as I made the decision, I was a bit more clear around my future and a lot of weight just fell off my shoulders.
"At least I know now it's not what-if - after the initial shock for me it was a pretty easy decision and I'm happy with it."
The decision is one that will be faced by footballers in a variety of codes, with a continuing rise in concussion awareness coupled with an increase in tricky choices for athletes. But the fact that choice is even presented shows the system is working and no player is being prematurely rushed back into the arena, concussion protocols be damned.
"I was treated really carefully," Afeaki said. "There was no pressure whatsoever for me to get back on the field early and have a crack. I had numerous meetings with specialists and that was all supported from the Chiefs and North Harbour and the NZRU. At the end of the day, they couldn't have done a better job and I'm really thankful for that."
Afeaki will also be thankful his post-playing years can proceed unhindered by headaches or dizzy spells, planning an initial break from the game before looking at opportunities in and away from rugby. "I'll always in some way be involved in the rugby environment, whether it's through friends that I've made or coaching or that kind of thing."NZME.
