Portland star playmaker Sebastian Blanco left early in the second half with an apparent leg injury. As he tried to run to a forward pass, Blanco went to the ground, grabbed the back of his taped left leg and immediately signaled for a substitution.
Portland will be without Dairon Asprilla for the conference final after he received a straight red card for violent conduct in second-half stoppage time.
