The Dynamo ran away 4-0 winners but the game was marred when Brian Ching and Geoff Cameron tangled with Dallas' Jair Benitez after the Colombian defender spat in Cameron's face.
Benitez claimed that he only spat back after Cameron had committed the disgusting act first but the Dynamo midfielder was not so sure.
"No chance, no chance," Cameron told the Houston Chronicle when informed of Benitez's claim. "If he says I spit in his face, he's an idiot."
"I think he's an unprofessional player. It's just one of those things that he came up to me and it took me every ounce of my energy not to punch him in the face, hit him or retaliate. But I'm a better professional than he is. I just kind of turned my shoulder a little bit and shrugged it off.
"The scoreboard speaks for itself. It was 3-0 and it was on his field when he played. It's one of those things that you have to let it rub off and not focus on it."
But Benitez defended himself for his unsanitary actions, saying: "No, he also spit (at) me. That's why I spit (at) him, but it's because he spit. He's a player that was telling me about everything. That's why he spit (at) me and I also spit (at) him."
China agreed with his Houston teammate that Benitez is indeed a dirt player in what is sure to a closely-watched tussle the next time the teams meet.
"I think he's a dirty player," Ching said. "We don't need that type of player in this league. He's a good player. But you definitely don't need that extra antic on the field. There's no room for it."
