Dundee United were reduced to 10-men against Aberdeen on Saturday, after referee Mike Tumilty decided the on-loan Cardiff City midfielder had dived.
However, manager Craig Levein thinks the decision was harsh, because Flood didn`t deliberately try to gain an advantage by going to ground.
“There are situations where its not a dive or a foul,” Levein told the BBC after the 1-0 win.
“Willo Flood was unbalanced, he knocked the ball past the player and he didn`t dive.”
“He wasn`t in the penalty box, its not like we would have gained any advantage and he actually had a shot at goal.”
“I feel for the referee, the pressure is on him to stamp out cheating and he`s come down hard (on Flood), but I don`t blame him.”
“This is an issue that has been in the spot light of the media for a while, ever since Gordon Smith suggested that we try to stamp it out.”
“That said, I want to stress that I am 100% behind stamping out diving in football, I`d like to make that clear.”
Although, Dundee United managed to recover from going down to 10-men and secured a late victory over Jimmy Calderwood`s side.
A 90th minute strike from youngster David Robertson gave Craig Levein`s side their first win on the opening day of season, since beating Dundee 2-1 at Tannadice in 1999.
