Back in 1972, Gray spent the next day after the FA Cup final win over Arsenal on the treatment table before being patched up and sent out to meet Wolves the following Monday night.
Leeds had so many Wembley injuries, Billy Bremner had to play up front with Wembley hero Allan Clarke. They lost 2-1.
"No, I don't still feel badly done to," Gray added. "That's away in the past. The only thing that concerns me is trying to pick up three points there on Sunday. It would be nice to go there and win.
"We are on a bit of a run. You would really like to win matches, especially at home, but if you're picking up points at least you still have that belief that you're going to be difficult to beat. Against Villa, we didn't play particularly well from an attacking point of view, but the good thing was that we didn't lose.
"I'm just pleased with the way the players have responded. I said when I took over that it's going to be a battle right to the end of the season. In our position, every match is crucial. The Wolves game is no different. We'll be going there to try and win, but if we pick up a point away from home we'd have to be happy."
