While Greig Laidlaw was on target with four penalties to seal victory, Jackson missed three from the tee and he is the only member of the starting XV to be released for domestic action this weekend when he will assume the kicking duties for Ulster from South Africa's Ruan Pienaar.
But Ulster teammate Best is convinced that Jackson will come back even stronger from his setback.
"When you're a professional player, not everything goes perfectly for you. Paddy's a fantastic talent, a great player with a great attitude," said Best.
"His general play was very good, but under the type of microscope that's on Test rugby every detail is analysed.
"It's unrealistic to think that you will go through your career without having moments when things didn't go so well.
"Great players dust themselves down and critically analyse what they did and try to get better the next week.
"Even at this young age Paddy has had a few moments at Ulster, but has bounced back strongly. That's the type of guy he is and why he will bounce back from this."
