This latest announcement comes as Jim resumed full training ahead of Friday night’s showdown with European champions, Munster, at Firhill (ko 7:45pm) following a knee injury sustained during Glasgow’s historic win over Toulouse in France almost ten weeks ago.
After putting pen to paper this morning, Jim said: “I’m really happy to have signed for another two years because the club is going places and there’s a great atmosphere both in the squad and in the stands at Firhill.
“I feel I’ve made real progress in the three years I’ve been with Glasgow and I want to stay here to try and make that next step up.”
Warriors head coach, Sean Lineen added: “James is a hugely energetic player and trainer, and if you cut him in half, you’d see he’s Glasgow through and through.”
