Northern Ireland have received a huge boost after scans showed no serious damage to Kyle Lafferty's knee.
The Rangers striker, who scored in his country's 1-1 draw with Poland at the weekend, was forced off late in the match.
It was initially feared that Lafferty's injury was a bad one and he was almost certainly out of Wednesday's crucial clash with Slovakia at Windsor Park - a game you can see live on Sky Sports.
However, scans have now revealed no serious damage for the target-man, who now looks as if he could be involved against the Slovaks.
"It felt good, it was a bit sore yesterday, but I iced it and looked after it," he told Sky Sports News.
"It felt good and I knew there was a chance the scan would come back good and it did."
Northern Ireland currently sit second in Group 3 and have a great chance of at least making the play-offs for South Africa 2010.
"It is going to be brilliant if we do make it," said Lafferty.
"For all the players involved, coaching staff and the fans as they have been exceptional.
"Every player wants to play at the highest level and I think everyone is buzzing that we are so close. Everyone is excited."
Should Lafferty not make the match then new call-up Billy Kee could be handed the chance to feature and Northern Irish Under 21 coach Steve Beaglehole has backed the Accrington man to make his mark.
"A lot of the time you wonder if the fear factor will kick in when you promote a player," said Beaglehole.
"But Billy will be able to cope, no problem. If he was required in the game, it would not faze him."
