After midfielder, Michael Carrington had put Black Rock in the lead with a bullet-header from six metres, both himself and Maxson Ramsey were sent off within seconds of each other.
Bethel United continued their excellent early-season form with similar 2-0 victories over Signal Hill and Lambeau F.C. while Black Rock also made it two victories in a row when they blanked Carnbee/Mt. Pleasant 2-0. Elsewhere, Golden Lane and Phoenix shared the points in an exciting 1-1 draw and whipping-boys Carnbee/Mt. Pleasant and Lambeau played out a goalless draw.
In the Eastern Conference, NLCB Mt. Grace stayed on top despite going under 3-0 to Leeds. Calder Hall stunned pre-match favourites Moriah Youths 3-2 and Youth Stars shut-out bottom of the table Goodwood United 2-0.
Moriah's lean run of form continued later in the week when they gave Goodwood their first point of the season after being held to a 1-1 draw.
