The NFL's investigation into reports of improper contact between players and NFL coaches has turned up no evidence of wrongdoing, a league spokesman said Thursday.

"Not at this point," said Greg Aiello, the league's senior vice president of public relations. "It's not an investigation, per se. We're monitoring what's taken place and follow up on various reports, then follow up on any specific information."

But there has been no evidence of improper conduct, said Aiello.

NFL clubs and their coaches are prohibited from contacting players during the lockout. Recent reports indicated that some coaches weren't following that procedure and were in contact with players conducting informal workouts. However, Aiello said the league found no evidence to support those reports.

In one instance, three teams were alleged to have made improper contact with undrafted free agents, but Aiello said that when the league launched an inquiry, nobody could detail specifics. In another instance, he said, it was discovered that a club contacted an undrafted player before the three-day draft had ended -- which was within the guidelines for that weekend.

"It was a misleading report," said Aiello. "At that point, there could be contact."

Bottom line: Thus far, there have been no misdeeds ... or, at least, no evidence of wrongdoing.

"Correct," said Aiello.
