A procedural error may cost the SuperSonics' Rashard Lewis an opportunity at free agency, according to a published report.

The New York Post, citing an unidentified attorney with knowledge of the contract language, reported on its website Tuesday that Lewis' agent, Tony Dutt, may have mishandled the paperwork that would have allowed his client to void the last two years of his current deal.

Citing the attorney, the report said that in order for Lewis to become a free agent, he had to declare his intentions in writing, delivering it personally or by registered mail on the later day of Seattle's last game or June 1, with a five-day window.
