Doc planted himself back in the World Cup frame with the winning goal for the Republic against the USA last week, but manager Mick McCarthy reflected afterwards that it was still unlikely the versatile Spur would make the trip.
Doc feels that he might have a chance if injury strikes between now and the naming of squad, but feels more optimistic and says he was 'dead and buried' not so long ago after suffering a broken leg in September.
"I think it's going to be a case of if an injury comes along I've got half a chance," said Doc.
"As it stands, and Mick's already said, it's unlikely. I've just got to go on what he says. If I do get the call though I'll be over the moon, but at the moment I can't see it happening.
"I was dead and buried at one point, but I think the goal has jogged a few people's memories that I'm still about. Who knows, I've still got a dream."
He partly agrees with the suggestion that a football man such as McCarthy is well aware of the value of a player with physical presense and the knack of scoring important goals.
"I haven't dismissed it, but it's a long way away for me. I think the gaffer has gone on record as saying I'm still a bit rusty so I've just got to try and get my fitness up.
"We've got a couple of reserve games still, and hopefully I'll be included in the first team squad on the bench - hopefully I can build my fitness up.
"The way things have swung in my favour has given me a great lift."
There has been much said on the subject of Gary Doherty's chances of boarding Ireland's flight to Japan and South Korea, but what does the man himself think?
