Kansas City, Kan. Sanna Nyassi and Collen Warner scored early in the second half, and the Montreal Impact rallied for a 2-1 victory over Sporting Kansas City on Saturday night.
Claudio Bieler scored on a penalty kick in first-half stoppage time for Sporting KC, prompting protests from Montreal that ultimately got coach Marco Schallibaum dismissed from the game. He missed watching Nyassi score the equalizer in the 47th minute, and Warner punching the go-ahead goal past Sporting KC goalkeeper Jimmy Nielsen in the 53rd minute.
The Impact (8-2-2) had to play a man down when Alessandro Nesta was given a red card later in the half, but they still held on.
Sporting KC (6-5-4) lost for the first time in four MLS games.
Tempers that had been running hot the entire game threatened to spill over when it ended as the two teams met on the middle of the pitch. Sporting KC coach Peter Vermes got into a shouting match with several Impact players, and staff members from both sides had to keep the teams apart.
Sporting KC dominated possession, but the Impact had the better scoring chances. Their best in the first half came when Felipe Martins got loose in the 39th minute. Nielsen strayed too far away from the goal and Martins sent a shot off the near post, and the ball deflected right back. Martins passed over to Marco Di Vaio, but his uncontested shot went wide left.
