Will Collier

An experienced tighthead prop, Will Collier brought more than a decade of top-flight know-how to Castres Olympique when he joined the Top 14 club in 2023. Born on 5 May 1991, he spent the entirety of his earlier professional career with Harlequins, becoming a mainstay of their front row across many Premiership seasons. Collier's reputation is founded on his scrummaging, where technique and raw power make him a formidable set-piece operator, allied to strong, low carrying in the tight channels. That form was rewarded with international recognition when he earned two caps for England in 2022. At Castres, his role is to provide set-piece stability and physical presence in one of Europe's most demanding domestic competitions, offering the front-row steel and experience that underpin a forward pack. A durable, uncomplicated professional, Collier is the kind of seasoned campaigner French clubs prize for the platform he lays at scrum time.
