GREGOR TOWNSEND is awaiting the results of a scan to determine how long he will be without Glasgow ace Rob Harley.

The Scotland international took a knock to an ankle during Saturday's 16-6 victory over rivals Edinburgh, with him definitely out for the return at BT Murrayfield this Friday night.

And Warriors head coach Townsend told SportTimes how the 24-year-old may be out for longer, depending on the outcome of a scan he underwent yesterday afternoon.

He said: "Rob got a scan yesterday and we should know by today. Who knows? He got a good whack on an ankle and knee. There are two things to look at. Chris Fusaro was confident when he injured an ankle over in Toulouse that he would be fine, but is out for three or four months.

"Robbo was sore when I spoke to him yesterday morning and we have to wait and see. He is definitely out this week.

"He was still in a lot of pain. He is in a boot, he is on crutches and with a six-day turnaround he is definitely out. He was going to be rested anyway."

Townsend is also waiting to hear how fly-half Duncan Weir is progressing after being rated doubtful for Friday's 1872 second leg with a bicep injury.

He said: "He was getting a scan last night and Stuart Hogg is getting a scan as well on a thigh strain.

"Both Duncan and Stuart are improving, but these are cautionary scans. Let us say they are precautions and we are still 72 hours away from the game.

"They didn't train yesterday and you see most of the improvement within day two and day three."

Meanwhile, assistant coach Kenny Murray said that despite the win at Scotstoun on Saturday, he is still looking for improvement from Glasgow when they go east later this week.

He said: "Obviously we were pleased to win and it is great to have the victory from the first leg to take with us to BT Murrayfield for the second.

"I thought our physicality was very good, particularly in defence, where our line speed was also excellent.

"We can improve on our work at the breakdown. Edinburgh were really physical and they made sure there were a lot of major collisions and we will need to combat that."
