Will Collier: Harlequins prop suffers knee ligament damage
Harlequins tighthead prop Will Collier will miss the rest of the season after suffering a serious knee injury.
The 23-year-old ruptured his anterior cruciate ligament in Saturday's 47-19 win over Castres in their European Champions Cup pool match.
Collier, who signed a new deal until the summer of 2018 earlier this month, came through the club's academy and made his senior debut in 2011.
He has played a total of 69 matches for the south-west London club.
