"It was a relief as well though," McNicol said of the operation. "Because I knew I'd be playing comfortable rugby again. Because last year, every time I went in to contact, it was just uncomfortable. I knew there was a long road ahead but I was always prepared for that."
Injuries in the outside back division of the Hurricanes this season saw the 19-year-old awarded a wider training group contract in April.
He had to put his sport and exercise studies on hold at Massey University and trade them in for a playbook, running alongside the likes of Ma'a Nonu and Conrad Smith at training.
McNicol waited patiently, continuing his strong form at club level, and further ailments in the squad mean he could make his Super Rugby debut via the bench when the Hurricanes meet the Chiefs in New Plymouth tomorrow.
"It worked out alright in the end," he said. "So obviously I'm pretty stoked to get an opportunity this weekend. Hopefully I can get out on the pitch and try and make a mark."
There's plenty of pace in his legs and he clocked 11.3s over 100m as a schoolboy.
Hurricanes coach Chris Boyd, who was one of the people that encouraged McNicol to go under the knife last year, said he had plenty of potential.
"He's got lots of upside, got a big left foot and can play at wing or fullback, so his time will come," Boyd said.
McNicol's body is cooperating with him again and he's a player to keep an eye on when the ITM Cup gets underway later this year as Wellington look to restore some pride following last season's dismal campaign.
