The NBA informed teams on Monday that organizations are prohibited from conducting in-person workouts or interviews with draft-eligible players until further notice, according to a memo obtained by ESPN.

NBA teams will be allowed to conduct virtual interviews with draft prospects, but are limited to four hours total for any single player, the memo said.

The guidelines are in place for an indefinite period during the coronavirus pandemic.

The NBA pre-draft process will be dramatically different for the 2020 draft, forcing teams to rely heavily on previous scouting and intelligence gathering. There are still uncertainties regarding how teams might gather crucial physical information on draft candidates.

Teams are also prohibited from requesting video of recent workouts that players might conduct outside of a team environment, the memo said. Teams can study only film -- such as college game and practice sessions -- that occurred prior to the NBA's suspension of play on March 11.

The NBA draft is set for June 25 at Barclays Center in Brooklyn.
