#4. Dominic Day (Wales)
Former Wales lock Day has come out of retirement to play for grassroots side Malahide in Ireland. Nearly two years after the former Scarlets and Saracens second-row retired from the game due to a knee injury, the 36-year-old has been tempted to put his boots back on for the All-Ireland League Division Two B team, and he made his debut in that tournament last Saturday in a narrow 28-24 defeat away to Belfast Harlequins.
