The home side were cruising with a 2-0 lead at half-time thanks to goals from Jonny Otto and Francisco Trincao.
However, the bruising Premier League contest was turned on its head in the 53rd minute on Friday night by Jimenez collecting a second booking following a clash with Leeds goalkeeper Illan Meslier.
Speaking after the game, Wolves boss Lage said: "Everyone saw what happened and now they have the chance to watch on TV.
"It's a body contact, Raul tried to win the ball. Bad decision – and he continued with the opinion he did a good decision.
"In the 45 minutes I think we were the better team. We were a much better team than our opponents. I am very proud of my players."
Wolves captain Conor Coady told Sky Sports: "It's a game we should win. We should still stay in the game but it is not a red card. I could go mad and kick off but for me it's not red. It's a fair challenge there was nowhere else it could go. These decisions are killing teams.
"I thought from the first minute he threw out yellows early on and I thought he lost the game. We don't feel like we were fairly treated.
"We look at ourselves first and foremost because we can defend better. But other people have to look at themselves as well.
"It's a massive factor in what has happened."
Jimenez, who had already been booked, collided with Meslier chasing a 50-50 ball.
Coady added: "I don't know where he's meant to go – he's not invisible, he can't go through the keeper. I don't know where he's meant to go or what he's meant to do.
"For me this is happening every single game for one team or another – it's happening to different teams – where these sort of decisions are happening and killing teams, and that's what it has done for us.
"We still created the odd chance on the counter-attack but the red card plays a massive part in it [the result] – if somebody tells me it doesn't, they are lying.
"It was a fantastic game of football and, again we are talking about referees and it should never be the case in this league."
