Atlanta Hawks coach Nate McMillan entered the NBA's health and safety protocols on Saturday.
McMillan's top assistant, Chris Jent, entered the protocols earlier in the week. With McMillan and Jent both unavailable, assistant coach Joe Prunty is expected to serve as the Hawks' acting head coach against the Portland Trail Blazers on Monday, sources told ESPN's Adrian Wojnarowski.
The plan will be for Prunty to take over until one of his two colleagues is cleared, sources said.
Prunty was 21-17 as the Milwaukee Bucks' interim coach in 2017-18 following the firing of Jason Kidd.
The league has had 11 head coaches in protocols at times this season. McMillan is the eighth head coach currently in protocols.
The Hawks took six of what had been their league-high 12 players in protocols off the list Saturday, including Kevin Huerter and Danilo Gallinari.
And while eight teams started the day with at least five players apiece in various stages of the league's health and safety protocols related to the coronavirus, the number of players on the list was trending downward.
By late Saturday afternoon, the number of players revealed by teams to be in the protocols was around 100, about a 20% dip from the highest known figure the NBA was dealing with earlier in the week. The numbers fluctuate on almost an hourly basis; some players are closer to a return than others.
