Big 'Doc' was a regular member of Mick McCarthy's plans in Ireland's qualifying campaign until he broke his leg in September.
He will nowe have to watch the two-legged tie on Saturday and Wednesday on television but he is trying to look on the bright side.
Now out of plaster, 'Doc' said: "The two games coming up for Ireland now are huge.
"I would love to be involved but I'm still not too bitter because even though I'm missing massive games and the team is doing so well I know I've been lucky with injuries.
"It's the first serious injury I've had and I suppose you say I was fortunate to do it now at Spurs rather than earlier in my career. Touch wood, I've been lucky.
"The World Cup is not my priority though. To get back into the Spurs team is my priority. The lads are flying at the moment and it will be really hard to get back in.
"The World Cup comes second because Ireland are also flying and I've only really been a bit part player. If I can get back in the Premiership then hopefully I can get back into the squad."
Gary Doherty would love to be involved in Ireland's World Cup play-off showdown against Iran - but insists next summer's finals are the last thing he's thinking about at the moment.
