OAKLAND, Calif. (AP) — Commissioner Adam Silver says the NBA needs to see definitive progress toward changing a hotly debated North Carolina law by the end of summer to ensure that the 2017 All-Star Game will remain in Charlotte.

Silver says he has been pleased by the direction of the discussions and would already be looking to move the game were that not the case. He remains optimistic that a solution will be reached to keep the game in Charlotte.

The law excludes lesbian, gay and transgender people from state anti-discrimination protections. It also blocks local governments from expanding LGBT protections, and bars all types of workplace discrimination lawsuits from state courts. The law also directs transgender people to use public toilets corresponding to the sex listed on their birth certificate.
