Liverpool-born hooker Johnny Matthews joined up with Dave Rennie's squad ahead of the 2019/20 campaign.
The hooker then impressed in his Scotstoun outings to earn a full-time contract for 2020/21, before repeating the feat ahead of the 2021/22 season.
Scottish qualified courtesy of his Glaswegian mother, Matthews had previously caught the eye in his outings for Boroughmuir in the Tennent's Premiership.
The hooker has an uncanny knack for try-scoring, having finished top of the Premiership charts with 19 tries in 16 appearances, as well as recording 29 tries in 26 appearances for Sedgley Park in 2016/17.
His first try in Glasgow colours came in December 2020, touching down in the 83rd minute against the Dragons at Scotstoun.
He has previously represented Scotland at under-18 level, as well as turning out for the Scotland Club XV.
Matthews made his first start for the Warriors in February 2021, packing down in the middle of the front row against Ulster at Scotstoun.
His efforts in the 2021 pre-season series and around Scotstoun saw him named as the McCrea Financial Services Warrior of the Month for September 2021, with the coaches recognising his impact around the club.
