"It was always going to be difficult against Hereford who play good football," Jones said.
"We allowed Hereford back into the game by giving away a sloppy goal - but that's Cup football for you sometimes.
"We had done the hard work and were making life easier for ourselves but we didn't defend properly, which gave them hope in the last few minutes.
"But I thought we fully deserved the victory."
"We were beaten by a very good side who are going well in the Championship.
"Having said that, I thought we gave it a real go in the last 20 minutes and we got ourselves into a few good positions.
"Being 2-0 down I thought we might have folded but I thought we gave it a good go. However, I do accept we have been beaten by a decent side and it's back to the league now."
