Jon Welsh won his first cap for Scotland after Allan Jacobsen was injured in the final minutes of the warm-up for the RBS 6 Nations match against Italy in Rome in 2012, and scored his first try against Wales in the championship match at BT Murrayfield three years later.
That outing paved the way for Jon to push his way into the thinking of naitonal team coaches - featuring in three out of four Summer Test matches - before earning selection in the 31-man squad for the Rugby World Cup 2015.
It was there that Jon featured in four of five games in teh tournament, starting the win over USA, and coming off the bench in the quarter-final defeat to Australia.
Glasgow born Jon was educated at Eastwood High School in Newton Mearns. Before signing a professional contract he had had three seasons with Glasgow Hutchesons’ Aloysians, and before that he was with Whitecraigs.
Throughout his GHA career he was a key figure for his all-round performances not just in his basic role at loose head, though it was on the other side of the front row that he played his two club internationals.
He was signed by Glasgow Warriors after successful appearances for Scotland in the club international against Wales and Ireland in February 2008.
His Scotland A debut followed in the 38-7 win against Tonga at Netherdale, Galashiels, in November 2009. Since his debut he has played a key role in Scotland A games against Ireland Wolfhounds (twice), Italy A, USA Eagles and the crushing 2012 Netherdale victory over England Saxons.
Before joining in the professional rugby ranks Jon was an electrician and enjoyed boxing.
