"He has followed my career," said Craig in . "He is in hospital but is on the mend and will be watching on TV."
Craig also hopes to use a positive result to thank his former Newcastle Falcons team-mates Doddie Weir and Stuart Grimes. It was Grimes' decision to take a break from the international stage that has opened the door for the Glasgow lock.
"I had been playing for West of Scotland, but the main reason I switched to the Falcons was the opportunity to learn alongside players of their stature, along with the likes of Springbok Mark Andrews and Garath Archer, the former England lock," said Craig.
"Doddie took me under his wing, while Grimesy kept his eye on me and made sure I was not late for games or training."
Craig is sure the move to Glasgow has helped to persuade Hadden to include him in the set-up. "I am more of a ball carrier than a jumper," he said. "I am not the heaviest second row, but I have put on weight and I want to use it to best effect."
Meanwhile, Glasgow's Dan Parks is grateful to Scotland coach, Frank Hadden, for putting faith in him to take on the Argentinians on Saturday. "It's very pleasing that Frank has shown faith in me for what is a very important and tough game and I'm very happy to get another cap under my belt," said Dan in The Scotsman.
"The Six Nations was obviously a tough time for me, I copped a lot of flak for my performances and with all the disappointment around at that time it was a big challenge for me to come back from that. But I think I've handled it pretty well.
"My form towards the end of last season was good and I've taken that into the start of the new season. Frank has been really good. He's a positive kind of guy, he's shown faith in me and I believe his style of coaching develops confidence.
"I'm really looking forward to pairing up with [scrum-half] Mike [Blair], he's a crafty player and hopefully we can get a good partnership going and, if the conditions are right, we can play some exciting rugby."
