Instead of flying straight home, Glenn diverted to his native New Zealand for a well-earned break and to catch up with family. He also played down suggestions that he had retired from the Test scene.
Glenn said: "It has been a very demanding few months, both physically and mentally and I need to recharge my batteries. Once I am refreshed I'll be back to battle for Glasgow - and then we'll take things as they come as far as Scotland are concerned."
While Glenn takes time out, team-mate Graeme Beveridge is desperate to get back into action after six weeks on the road without any action. Graeme is now focused earning a regular starting slot for Glasgow ahead of new signing from New Zealand, Sam Pinder.
"It is exciting to be going back to Glasgow now and hopefully to get some game-time under my belt."
Graeme played down his chances of lining up against Ulster in Friday's Celtic Cup semi-final at Hughenden (ko 7.30pm). He said: "It is probably too much to expect to be picked so soon after the trip. I would love to be involved, but if I went straight back in, it might be a bit unfair on the guys who have got them this far in the competition."
