Villa boss Roberto Di Matteo dropped and fined Jack Grealish, who earns around £15,000-a-week, after a club investigation into his conduct following reports he partied at a Birmingham hotel last weekend but the midfielder will be available for Tuesday's trip to Barnsley.
Di Matteo insisted the matter is now closed but warned Grealish he cannot continue to make mistakes after the Italian became the fourth Villa boss to admonish him.
He said: "We've fined the boy and he was suspended for today's game. It's not the first time but he needs to learn from the past and the only one who can do that is himself. He needs to make the right decisions.
"He's 21 now and needs to understand what kind of career he has ahead of him. as long as he does what he's supposed to do we will treat him like everyone else. every player you have to speak differently to and I have my way to speak with Jack."
Without Grealish Villa struggled for much of the game but roused themselves after Mile Jedinak had a goal ruled out for offside with 22 minutes left.
Jordan Ayew then hit the post before Tshibola's header but despite his goal Villa have still only won one of their opening nine games since relegation last season.
They had previously conceded four goals in the last five minutes of games to drop seven points this season but Di Matteo believes Saturday's fightback will end their late nerves.
"I really hope so, against (Nottingham) Forest we turned the game around but unfortunately we conceded an equaliser. Today we got it back and pushed on to find the second," he said with Villa 17th in the table. "There's certainly a degree of belief that we're still in the game and can win.
"Our challenge is to turn the draws into wins because we have drawn too many games and that's what the table reflects."
