"We had a lot of youngsters in there tonight and they haven't let anyone down." siad Jones.
"I can't fault them. We wanted to go through, and the team nearly did it, but we probably lacked a little bit of awareness at the death.
"This has given the youngsters a great taste of FA Cup football. They went out there and gave everything they had and we are disappointed we have gone out."
Tony Pulis also made changes. 10 in total from the side that started in the Premier League last weekend. He defended his decision to use his sqaud players.
"I will use the squad again at Wolves, very much so." he stated.
"It was a tough game, both sides made loads of changes, and we are pleased to have come out with a win.
"I don't have to justify (selection) to anyone apart from my chairman.
"We've got a 25-man squad and we pay players good money whether they are in the team or out of the team.
"We wanted them to have a go tonight and they did. That is all you can ask for."
On Cardiff, Pulis said, "Cardiff haven't played their top team against us, but they have got a squad as good as any in the Championship.
"I expect them to be there, without a shadow of a doubt. With the quality they've got you win more games than you lose."
