Jason Williams is seriously considering a return to the NBA less than a year after retiring following a career that saw him play with Sacramento, Memphis, Miami and the Clippers.

"The free agency period opens up July 1, and I should be good to go then," Williams told the Daily Mail.

"If I do decide to play, I'd like to play two or three more years. That's about it.

"I'm not 100 percent that I'll play again, but it's more than 50/50 that I'm going to try. But if it doesn't happen, trust me, I won't lose any sleep."
