Vakalahi played rugby throughout his time at Penn High School, playing Number 8 and helping the side to a 3rd place finish in Boys High School Rugby Nationals, also claiming a state championship. He was named a U17 All-American and was nominated for the best high school player in the country. Following high school he attended Davenport University where he was named to the Top Freshman D1A Team and was selected to the USA U20s camp. He featured for Old Glory DC during their exhibition season in a game against Shannon Rugby Club, before joining the USA U20s for a two-game series against Canada in the World Rugby Trophy qualifier.

Vakalahi signed with Old Glory DC ahead of their inaugural MLR season in 2020, appearing in all 5 games and starting 2 before the season was cut short due to the COVID-19 pandemic. He sustained an injury in the 2021 pre-season that sidelined him for the entire year, before earning 6 more appearances for the Flags upon his return in 2022. Following the 2022 season, Vakalahi played with the Houston SaberCats academy side, Rugby HTX, during the 2022 American Rugby Premiership season. After his performances with Rugby HTX, Vakalahi signed with the Houston SaberCats for the 2023 MLR season, earning 3 appearances while also playing for Rugby HTX once again and beginning the transition from prop to hooker. Vakalahi didn’t feature for an MLR side in 2024, but spent the year playing with the Chicago Hounds academy. On December 26th, 2024, the Chicago Hounds announced that they had signed Will Vakalahi to an MLR contract for the 2025 season.
