Vancouver Whitecaps defender Andy O'Brien suggests diving, or simulation, is simply part of the game.
"There are people that dive in Europe and there are people that dive here," he told the Vancouver Sun.
"I suppose there's a level that you'd like to think is acceptable. And I've always been one, personally, that once a referee gives a decision, there's not really a lot you can do about it."
Kinnear made the comments after FC Dallas striker Kenny Cooper went down easily to win a free-kick in Houston's 3-2 defeat on the weekend.
