This from the Fulham messageboard is spot on:
"Forgive me if this has been posted elsewhere but if it has I've missed it. IMO Cardiff gained a huge psychological boost last night with that late equaliser. If they'd scored first and Sheff U had equalised late, they could have been a bit deflated, 2 points dropped etc. But to come back so late, reinforcing the 'we never give up and are never beaten' feeling will have been a real tonic for them. I hate to say it but I think they'll be pumped up after that."

The late goal will be a huge boost for the players, you saw what it meant to them with the celebrations
