San Jose Earthquakes president Dave Kaval has released a statement on behalf of the club in relation to comments made by Alan Gordon on Sunday night.
The Quakes forward allegedly used a homophobic slur directed at Portland Timbers midfielder Will Johnson, who eventually scored the winner in the 79th minute, in the 1-0 result.
Kaval said the club did not support Gordon's views and did not condone his use of inappropriate language.
"We are working hand in hand with the league right now on this very serious matter. Alan's comments do not reflect the views or beliefs of our organization. We have always promoted an atmosphere of acceptance and equality in our stadium and amongst our diverse and passionate fans," read the statement.
"I am appalled by the use of the hurtful language on the pitch last night. We will use the collective energy and resources of our club to foster an inclusive environment for all of our fans. I hope to use this deplorable incident as a tool to help eradicate offensive language of this kind.
"For our fans, I know the organization has let you down. I will do my best to take the necessary actions to make sure we once again can be viewed as a beacon of diversity, community, and equality."
