The length of the 28-year-old's new deal has not been disclosed, but will see him extend his time at The Stoop into an 11th season.

Tight-head Collier has made 164 appearances for Harlequins since his senior debut in 2011.

"It was an easy decision to stay at the club I've supported since I was a kid, it means so much to me," he said.

Collier follows team-mates Joe Marler and Alex Dombrant in committing his future to Quins.
