Reading close the gap on Wolves at the top of the table to just two points
Neil Collins' own goal after only 61 seconds secured victory for Reading and closed the gap on Championship leaders Wolves to just two points.
Wolves had chances to level with Andy Keogh stabbing Matt Jarvis' cross wide from close range.
Noel Hunt almost increased the lead for the hosts but his dipping free-kick was well saved by keeper Wayne Hennessey.
Deep into injury time Collins completed a miserable night by being sent off for swearing at a linesman.
Reading manager Steve Coppell: "I'm not even thinking about the championship. You'll get my bland answer that it's one game at a time.
"The result is all important. The goal was not exactly something we've been working on but you take what you can.
"There wasn't much space for anyone to play football. We are two similar sides in the way we play and the shape we keep so it was always going to be difficult to break the deadlock.
"There is a third of the season to go and it is all to play for. I see it as psychologically important but not significant as to who goes up. It is three points and at this stage it doesn't matter who it comes against."
Wolves manager Mick McCarthy: "Apart from the goal which is a defining moment I'm delighted with how we played.
"We scrapped to the bitter end and they've had a right go. I've no problems with them.
"I haven't asked the question why he (Collins) was sent off as I thought I'd better calm down first but I think he upset the linesman's feelings.
"We are still in the front and it's impossible to go through a season without a bad run. It's how we respond to it."
