The report into a case of alleged bullying among players at the Miami Dolphins will be published later this month.
Attorney Ted Wells, who was appointed by the NFL to look into the matter, says that he will release his report late next week or the following week.
The investigation follows allegations by tackle Jonathan Martin that he was harassed by teammate Richie Incognito, who was suspended for the final eight games of the season as a result.
Martin left the team during the 2013 season as a result of the alleged comments.
