The Boston Celtics were awarded a second-round pick from the Oklahoma City Thunder in the 2013 draft as part of a ruling in a trade disclosure dispute.

NBA Commissioner David Stern announced the ruling Tuesday.

It involved the medical condition of forward Jeff Green, who was acquired in February 2011 in the trade that sent Kendrick Perkins to the Thunder.

Stern "found that there was no evidence of bad faith or any intent to withhold information on the part of Thunder management or its physicians," according to a release from the NBA.

But the commissioner also found that cardiologists for the Thunder possessed information about Green that was not shared with the team's management that should have been disclosed to the Celtics.

Green had surgery Jan. 9 to repair an aortic aneurysm that was detected during a physical on Dec. 9. He played 26 games for the Celtics last season after the deal but sat out the entire 2011-12 campaign.
