Alvaro Saborio and Fabian Espindola scored for RSL, but it managed only a 2-2 draw with Sporting KC in an exhibition game on Tuesday night in Arizona that was abandoned in the late stages after a bench-clearing brawl.One witness said on Twitter that he saw the game and that the incident was triggered by a "dirty cleats up" tackle by KC's Roger Espinoza on RSL's Javier Morales. Coach Peter Vermes of Sporting KC confirmed to the Kansas City Star that a rough tackle by Espinoza sparked the brawl.Team officials in Utah who were receiving reports from colleagues at the game said the referee then mistakenly red-carded Sporting KC's Omar Bravo as the benches cleared. They claimed that Bravo returned to the scrum on the field and kicked Morales in the head before the game was called off, something Sporting KC officials emphatically denied."He had nothing to do with this," team spokesman Rob Thomson said.Like most of the RSL officials, Thomson did not attend the game. But he said he spoke with about eight players and several fans who did, and all of them said Bravo did not kick Morales. "He did not  in any way, shape or form," Thomson said. "He was the last one in the deal. … That's what everyone has said."Nobody on either team was injured, officials said.
