Glasgow have been hit with a serious setback after learning that Scotland prop Jon Welsh will be sidelined for six months.
Welsh was injured during training before Scotland's win over Australia in June and had to undergo surgery on his shoulder.
Gregor Townsend takes over as Glasgow coach next season and he admits it is a massive blow to lose one of his scrum lynchpins for such a long spell.
"It's clearly disappointing for Jon and the club as a whole that he will miss a substantial amount of rugby in the first part of the season," Townsend said.
"He will receive excellent care and attention from our medical team as he recovers from the injury, and we look forward to welcoming him back to the fray in due course.
"On behalf of everyone at the club, I'd like to wish Jon all the best with his rehabilitation. He's a positive character, which will stand him in good stead for the challenges ahead."
