Golden State Warriors head coach Steve Kerr has tested positive for COVID-19 and will miss Game 4 against the Memphis Grizzlies.

Assistant coach Mike Brown will step in as acting head coach – a role he is familiar with.

During the Warriors' 2017 championship run, Brown went 12-0 as acting head coach in the playoffs as Kerr was sidelined for an extended period, with the Warriors ultimately finishing that postseason with a 16-1 record.

It is interesting timing for Brown, who was announced as the next Sacramento Kings head coach on Sunday.

He has been with the Warriors since 2016, after spending 10 years as a successful head coach beforehand, winning over 61 per cent of his games with the Cleveland Cavaliers and Los Angeles Lakers.
