Webb undergoes surgery

The scrum-half was helped off just before the hour mark at Scotstoun, and will have an operation in London to repair the damage.

Medical Performance Manager, Chris Towers, confirmed the news, saying:

"Rhys had a scan on Monday which excluded any signs of ligament damage. However, he has gone to London for keyhole surgery to deal with a cartilage problem. Following discussions with the surgeon post-operation, we will be in a better position to discuss any potential return to play date."
