Afterward, Donovan explained that since one of his players had been racially abused in a game just a week ago ... they weren't going to stand for any kind of insensitive comments or actions on the field going forward.

"We went through a really hard incident last week in the L.A. match and we made a vow to ourselves, to our community, to our players, to the club, to USL, that we would not stand for bigotry, homophobic slurs -- things that don’t belong in our game."
The USL says it's investigating the incident, adding in a statement, "Foul and abusive language of any type has absolutely no place in our society and will not be tolerated in USL matches."
For Flemmings' part, he denies ever saying the comment ... writing in a post on social media, "At no point did I say a homophobic slur towards Collin Martin."
"I do not know Collin personally, but I respect all of my opponents equally, Collin included."
Flemmings continued, "I am disappointed by San Diego's actions this evening as I have been mauled and ridiculed online with no opportunity to defend myself ... I stand in solidarity with the LGBTQ+ movement."
