Norwich missed a second half penalty as bottom club Preston came away from Carrow Road with a 1-1 draw. The result leaves Norwich fourth while Preston remain 10 points from safety.
Canaries boss Paul Lambert said: "When penalties go in they look good however they are taken, and when they don't go in it is obviously a missed opportunity.
"Basically whilst Wes (Hoolahan) felt confident to take the penalty the way he did, he certainly wasn't being disrespectful to their keeper. He didn't have to hold his hands up and say anything after the game - 26,000 people saw what happened.
"I don't tell players how they should take penalties but I don't think he'll be taking one again like that while I am manager.
"I think it's affected his confidence after that but I'm not going to sit here and criticise Wes.
"He has been excellent for me in the 18 months and has done lots of good things, helping us to pick up a lot of points.
"Now it's just a case of putting this behind him and moving on to the next game."
On the match as a whole, he added: "This was never going to be an easy match for us because Preston are fighting for their lives at the bottom of the table.
"They have picked up a number of good results recently against some of the top sides and were always going to make life difficult for us.
"I'm always confident that we will create chances and I certainly thought we created enough today to have won the game but at the end of the day we didn't get beat and a few other results have gone our way.
"Who knows? It could end up being a huge point."
Preston boss Phil Brown admitted the point came at a cost.
"We got a good point but it has been a bad day for us in terms of injuries.
"We lost Andy Lonergan with a flu bug leading up to the game and then in the warm-up Nathan Ellington has turned his ankle.
"In the end it was all hands to the pumps especially after the last injury when David Gray had to go off. But the boys are giving me everything at the moment and we held out for a fantastic point.
"It was a good result here but it goes without saying that we need three points in the position we are in now.
"But four of our last five games have been against teams going for promotion and if it hadn't been for a late Burnley winner last week we would have been unbeaten in that spell, so we were obviously doing something right.
"We just need to take the shackles off by getting that first win - and I'm convinced that if we can do that more will follow. We've got Leeds at home on Tuesday and that would be a good time to start."
On the missed penalty he added: "I can never understand why players do that. To my mind he showed a little bit of disrespect to our goalkeeper so I am glad Iain Turner has got a penalty save out of it."
