Promising early form was interupted by a broken leg that kept him out until January only for the winger to break his hand playing for Gael Force in the British and Irish Cup.
Rob marked his return with two tries in the win over Leinster two weeks ago and he's eager for more as Glasgow bid for a home game in the Magners League play-offs.
“When I was hit with that second injury I thought my season was over,” he said in the Times. “It is great to be back, I was pretty happy with my two tries last week and I’m looking to kick on from there."
Rob will ine up against fellow Scotland international Sean Lamont who joined the Scarlets last summer. "It will be the first time I have played against Sean, I’m looking forward to it, two people who like physical rugby though you can never predict how the ball is going to run.”
