The keeper was fined an additional VND10 million ($432). In the 88th minute of the game between Can Tho and Cong An Nhan Dan (CAND) last Friday, Vu fouled a striker inside the box, prompting referee Do Anh Duc to award CAND a penalty and Vu a yellow card.
After Vu had successfully blocked the penalty, he ran over and slid onto his knees in front of Duc in provocation.
"When I rewatched the video, I realized my behavior was totally inappropriate. With little time left, a penalty would have cost us the game. So, after I blocked it, I let my emotions take over," Vu said.
Vietnam Football Federation (VFF) subsequently suspended Vu for three V. League 2 matches from April 4 to 17.
"Although Vu made no physical contact with the referee, his provocative action is very inappropriate and deserves to be punished. A player must know his limits," the head of VFF’s Disciplinary Department Vu Xuan Thanh said.
VFF also suspended referee Duc for a few games since he failed to award Vu another yellow for his behavior, according to FIFA regulations.
