Adrian Wojnarowski of Yahoo! Sports reports four players were fined $15,000 apiece for participating in the UW alumni basketball game.
According to Wojnarowski -- who is so well-sourced, he knows what you are doing tomorrow before you do -- Isaiah Thomas, Tony Wroten, Quincy Pondexter and Spencer Hawes were fined by the league.
UPDATE: The league confirmed to the TNT that a group of players were fined for playing in the game because it was not sanctioned by the NBA. A spokesperson would not go into detail about which players, how much and specifically why.
The key here is the date: According to the NBA's collective bargaining agreement, players cannot play in a public offseason game prior to July 1 or after Sept. 15. The alumni game was June 23.
When asked at the end of the event if they would do it again, Washington head coach Lorenzo Romar said that he was interested, but would have to do some things better. He mentioned concern about contracts and such, but nothing about not having league approval.
Any organized game that NBA players participate in is subject to the foils of the league. That's part of the reason it was so difficult to put together a local NBA charity game during the last NBA lockout. The league has all sorts of rules and sanctions around the arrangements.
In the case of charity games -- which the alumni game obviously was not -- those rules are in place to guarantee money goes to charity (a minimum of $100,000) as opposed to someone pocketing the money while using the NBA brand. But, the point is, these things are never easy to put together because of the league's set up.
It's unclear right now if other NBA players, like Terrence Ross and Nate Robinson, will also be fined for their participation.
