Reading manager Brian McDermott was adamant Cardiff should not have been awarded their second-half equaliser in the 1-1 draw because the ball had not crossed the line.
Jay Bothroyd saw his long-range strike come back off the underside of the bar and referee Andy D'Urso pointed to the centre circle after the linesman signalled for the goal.
But McDermott said: "He guessed. He couldn't be sure the ball was over the line. It wasn't a goal. It was as simple as that."
He added: "The linesman killed the referee and he will be embarrassed when he sees it again. I knew straight away that it wasn't over the line and it took me just three seconds after the game to view it again and confirm it wasn't over. It was a really poor call.
"It's 2010 and we still don't have goal-line technology. It is becoming farcical.
"But the last thing you want to hear is another manager moaning. I didn't think we would be talking about a draw when we were ahead but all be forgotten in a week's time."
