Glasgow: Jonny Gray set to return for Pro 12 clash with Ulster

Glasgow captain Gray has only played three club games this season because of Test commitments

Scotland lock Jonny Gray is set to return to action for Glasgow when the Pro12 champions step up their bid for a play-off spot against Ulster on Friday.

Gray tore a chest muscle in Scotland's Six Nations win over France, ruling him out of their final match in Ireland.

But along with fly-half Finn Russell, who also missed the Dublin match after concussion, Gray has been declared fit.

"It's great having Jonny back for the run-in," said Warriors forwards coach Dan McFarland.

"While the international players have been away, the guys who have been here have excelled. But Jonny is an excellent player, in my mind a world-class player already at a young age."

Glasgow, sixth in the table, have won four games in a row since losing 13-10 at Ulster in early February and are now four points behind the Northern Irish province in fourth, with a game in hand.

With Gray, Russell and the rest of their Scotland contingent - Glasgow had 11 players on duty in Dublin - returning to the fray, lock Rob Harley admits there has been a step up in intensity at training.

"You know when the players around you are of a very high quality, you have to lift your level and perform everything to a very high standard," he told BBC Scotland.

"It is challenging but fun as well to be training at that level."
