Byron McGuigan went over for Glasgow

Glasgow tries came from new boys Byron McGuigan and Taylor Paris. Ruaridh Jackson converted both scores and added a penalty. Glasgow looked like they would snatch the win but a late pushover try, with Jackson in the sin-bin, gave Castres the win.

Glasgow coach Gregor Townsend told www.glasgowwarriors.org: "It’s good to get a solid 80 minutes under our belts against a side who are only a fortnight away from competitive rugby in the Top 14.

“We didn’t start all that well, which perhaps wasn’t a huge surprise given the heat and the fact this was our first time on the pitch together, but we really picked up in the second half and played some impressive rugby.

“Taylor and Byron took their tries very well, and I was really pleased with the shift that Tommy Seymour, Peter Murchie and Fraser Thomson put in.

“The pack worked very hard for each other as always, and Angus Macdonald showed just why we brought him here in the way he defended and read the game.

“I was impressed with [Elite Development player] Adam Ashe at No.8, and I’d also like to mention [Dundee lock] Andrew Redmayne and [Gala scrum-half] George Graham who have done everything we’ve asked of them all week and didn’t look anything like out of place when they came on.

“Clearly, we’d have liked to win, but the object of the exercise was getting ourselves up to speed and working on our patterns and understanding, and on those fronts we can certainly be satisfied with what we achieved.”
