Skipper Chris Morgan and substitute Lee Hendrie had to be separated by colleagues as they appeared to blame each other for Lee Croft's stunning late strike.

The goal came down Hendrie's flank, and the former Aston Villa man did little to block Croft's surging run as he played a one-two with Jamie Cureton before blasting the ball past Paddy Kenny.

Morgan might also have blocked the shot and he and Hendrie went forehead-to-forehead before being pulled apart.

There were also reports that the pair continued their argument in the tunnel but Blackwell denied that the row had got physical.

"There is no truth in that whatsoever," said the manager.

As for the disagreement during the game that was there for everyone to see, Blackwell added: "You want players to show passion for the club and passion for their performance.

"There are too many players that walk away now and don't really care.

"If everyone had been patting themselves on the back after Norwich had scored I would have been grabbing people by the throat."

Blackwell felt his side had been the better team and would have won but for a stellar performance by Canaries keeper David Marshall.

"The match should have been over by half-time but if you don't take your chances in this game there is always a risk that you will get punished and this is exactly what has happened today," he said.

"You certainly would have thought we were the away side today because we really took the game to them but the lad Marshall has made one or two great saves, including one near the end to keep them in it.

"It goes without saying that it is bitterly disappointed to come away from here with nothing but full credit to Norwich to taking their chance when it came their way.

"They have taught us a valuable lesson today."

Norwich manager Glenn Roeder felt justice was done when Croft fired home his last gasp winner.

"What pleases me most about this win is that we have finally got what we deserved out of the match," he said.

"On more than one occasion this season that hasn't been the case. It was a tough game and David Marshall has had to make one or two saves, certainly a lot more than he has made so far this season.

"But overall it would have been an injustice had we got nothing out of this game and it just shows the importance of the late save he made. That was as important as a goal to us."

Roeder was delighted to see Croft net his first goal of the season to earn Norwich the points.

"At long last Lee Croft has bought a lottery ticket and it has proved to be the winning one," said the City boss.

"We've been going on at him in training to use his left foot as well as his right and he has been rewarded with a goal.

"Hopefully there will be more to come from him now because we need people all over the pitch chipping in with goals and I think Lee Croft should be a half dozen goals a season man at the very least."
