The 70 scouts believed to want to view Hampton during his time in Memphis are also in town to observe a pro day hosted by college team the Memphis Tigers so they can see projected number one pick James Wiseman.
But with some carefully placed words to the NBA's administrators, the league has allowed the scouts to attend the practice session tonight and shoot around tomorrow in the build-up to the game, and also ahead of the fixture against the Oklahoma City Thunder on Friday.
"It might be a record for the fastest change that the NBA has ever made, but they got it done," said Breakers owner Matt Walsh.
He adds it's a huge relief as it's extremely important for them to show they can look after future draft prospects so they can lure others to the Breakers in the future.
"It's massive, it's not just important for the Breakers, it's important for RJ, it's important for our relationship with all these NBA teams.
"I think the NBA looked at it objectively and they made the right decision."
The Breakers key argument was that Hampton was a professional unlike college athletes, being scouted by professional teams, so the rule shouldn't apply.
