Head coach Sean Lineen today unveiled 25 year-old, Tom Ryder, as the latest edition to the Glasgow Warriors pack.
The 6ft 5in, 18st 6lb lock, who qualifies for Scotland through his Glaswegian father, Paul, joins from English Premiership outfit, Saracens, on a two-month loan.
Head coach Sean Lineen, said: "I'm delighted with the great support I've had from Chief Executive Kenny Baillie and Scottish Rugby to secure the services of such a quality individual.
"He's a very mobile, modern-day lock and is incredibly hungry. You can see his ambition when you speak to him and I applaud his attitude.
"Brendan Venter [Saracens director of rugby] was very accommodating – the situation works for both clubs. They're very ambitious and Tom [Ryder] needs game time while we get a quality lock, desperate to force his way back into regular rugby.
"At present this is a loan arrangement to bolster our squad as we seek to match and surpass our achievements last season, which will ask a lot of an already young squad."
A mainstay throughout England's international age-grades from under-16 up, Tom Ryder moved to Saracens from the youth set-up at Leicester Tigers in 2005 aged 20, and made his full debut against Wasps in the Anglo Welsh Cup before getting his first English Premiership start at Welford Road a few months later.
Ryder has since been a regular in the Saracens matchday squad since breaking into the first team for the final six games of the 2005/06 campaign when impressive displays helped guide the club away from the threat of relegation.
After spending the opening three months of the 2008/09 season playing for Taranaki in the Air New Zealand Cup, Tom Ryder returned to the club to force his way back into the first team squad and has been a regular ever since, turning out for the Sarries on total of 95 occasions.
Speaking after his first training session at the Scotstoun Sports Campus, Tom Ryder said: "Glasgow had great season last year so I'm delighted to get the opportunity to be part of a fantastic squad and train in world-class facilities.
"There tends to be more rugby played in the Magners League; the teams are a lot more willing to play rugby which I think will suit my style of play where the players play in a less confined structure.
"I pride myself on being a physical and ball-carrying lock and am looking forward to bringing my experience to Glasgow and helping them match and better their successes last season."
