The former Wigan winger was sent off late in his side's World Cup qualification draw and has labelled Carlos Amarilla a "disgrace" for failing to award a second-half penalty
The former Wigan star was later sent off by Amarilla for a foul on Diego Godin, but had previously been irked by referee Amarilla's decision not to award Ecuador a second penalty in the match after Christian Benitez went over in the area in the second-half.
Felipe Caicedo had put the Ecuadorians ahead prior to Edinson Cavani's equaliser and, having been shown a second yellow card moments before the full-time whistle, Valencia vented his frustrations at the referee after the match for failing to point to the spot just after the hour mark.
"This referee is a clown," he said. "How come he didn't give us that penalty? We are in Uruguay, we are not on another planet.
"He did the same in the last World Cup qualification campaign. He's a disgrace. A total clown."
The result leaves Ecuador in third place in the group in the South American section of World Cup qualifying while Oscar Tabarez's Uruguay are just a point behind in fourth spot.
