At 26 years old, Plummer (1.85 m, 96 kg) will therefore be the basic man of the Clermont game and will replace the Argentinian Benjamin Urdapilleta, 38 years old, who will retire at the end of the season. Able to also play in the center, Plummer will participate, before joining Clermont next summer, in the Super Rugby season with the Auckland Blues franchise, which spotted him very young and which is now coached by Vern Cotter , former manager of Clermont between 2006 and 2014.
