William St Lawrence Webb Collier (born 5 May 1991) is an English professional rugby union player who plays as a tighthead prop for Top 14 club Castres Olympique.
Collier is a front row specialist who cites his interest in the 'dark arts' (of scrummaging) inspired in part by Chris Ritchie, a veteran London Welsh RFC player and Joe Launchbury, a former England Rugby international. [1] His first club was Rosslyn Park F.C. where he began at six years old and played in their mini, youth and First XV squads. [1]
Collier joined the Harlequins academy at the age of fourteen. [2] In January 2011 he made his club debut for Quins against Wasps RFC in a 2010–11 Anglo-Welsh Cup fixture. [3]
Collier represented England U20 during the 2011 Six Nations Under 20s Championship and appeared as a substitute in the last round as they defeated Ireland to complete a grand slam. [4] Later that year he was a member of their squad at the 2011 IRB Junior World Championship ands came off the bench in the final which England lost against New Zealand to finish runners up. [5]
Collier was on the substitutes bench when Harlequins overcame Leicester Tigers in the 2012 Premiership final to become league champions for the first time in their history. [6] In March 2013 Collier started for the side that defeated Sale Sharks to win the Anglo-Welsh Cup. [7] He scored his debut try for Harlequins in a European Rugby Champions Cup defeat to La Rochelle in the pool stage of the 2017–18 season. [8]
Collier was included in the senior England squad for their 2017 tour of Argentina. [9] On 10 June 2017 he made his Test debut as a substitute against Argentina. [10] A week later Collier scored a try as England won the series. [11] Ultimately these were his only two caps. [2]
In the 2020–21 season, Collier was a replacement in both the Premiership semi-final victory over Bristol Bears and the final against Exeter Chiefs on 26 June 2021, as Harlequins won the game 40–38 in the highest scoring Premiership final ever. [12] [13] The following year saw Collier start for an England XV side in an uncapped match against the Barbarians. [14]
In his final season at Harlequins Collier started for the side that were eliminated by Toulouse in the semi-final of the 2024 Champions Cup. [15] After more than a decade with Harlequins making 240 club appearances, Collier joined Castres Olympique for the 2024–25 season. [2]
