NBA commissioner Adam Silver and NBPA executive director Michele Roberts will host a call for all players today as teams are preparing to reopen practice facilities for voluntary, social-distanced workouts in areas where that has been permitted by local public health officials,

The call with Silver and Roberts is intended to be an open forum for players to address any concerns or ask any questions they have, sources said.

Three teams — the Portland Trail Blazers, Denver Nuggets and Cleveland Cavaliers — have told ESPN they plan to reopen today, while several other teams said they hope to open next week. The Houston Rockets had planned to open their facility todaybut reconsidered in collaboration with players and staff as well as Texas Gov. Greg Abbott’s directive for gyms not to open until May 18.

Other teams, meanwhile, say they’re in no rush to return.

Those include the Los Angeles Lakers and the Dallas Mavericks, whose owner, Mark Cuban, said Wednesday that teams’ inability to test asymptomatic players for the virus makes a return to facilities right now not worthwhile.

“Even though we can try and take all different kinds of precautions, it’s just not worth it — particularly when our guys are staying in shape and they’re going outside and shooting on outdoor hoops and working out in various ways,” Cuban said on The Athletic’s “77 Minutes in Heaven” podcast. “So I just don’t think the risk is worth the reward.”

Teams opening practice facilities for volunteer workouts will be able to designate six assistant coaches or player development personnel to provide supervision of player workouts on the courts, a source told ESPN’s Adrian Wojnarowski. Head coaches will not be allowed to participate or observe the player workouts, sources said.
