PRO has announced the referee assignments for the first legs of the MLS conference finals.

Juan Guzman will be in charge of the Eastern Conference final between the Montreal Impact and Toronto FC, while Chris Penso will lead his crew for the Western Conference final involving the Seattle Sounders and Colorado Rapids.

Guzman has not officiated a game involving the Impact or TFC all season long. He refereed 15 MLS regular-season matches in 2016.

Penso was in charge of the Sounders’ 2-0 loss to the New York Red Bulls on June 20 and also officiated four Rapids games. Their only win came on Aug. 7 at the Vancouver Whitecaps. He did not send off a single player in any of the five matches.
