Goodell: Leaks are 'conduct detrimental' to NFL

NFL Commissioner Roger Goodell
is not happy about confidential information from the scouting combine making its way into the media -- and he's looking for the team officials responsible for the leaks.

Goodell, reacting to reports last week that three likely top-10 draft picks admitted trying marijuana, has sent a memo to all 32 teams
warning against leaking such information, USA Today reported Wednesday.

In the memo, Goodell wrote that leaking such information would be considered "conduct detrimental to the game" and that violators would be subject to unspecified discipline.

"I'm troubled by the breach of confidentiality," Goodell told USA Today. "Whenever you get into these situations leading up to the draft, you have a lot of misinformation put out there."

Last week, Pro Football Weekly reported that according to two unnamed team officials, Georgia Tech receiver Calvin Johnson, Clemson defensive end Gaines Adams and Louisville defensive tackle Amobi Okoye admitted using marijuana. The league is investigating the report.

Those admissions were given during videotaped interviews that are conducted during the combine and distributed to all 32 teams. Players are encouraged to be honest during the interviews.

It's not the first time that confidential data from the scouting combine has found its way into the media in advance of the draft. Last year, reports surfaced that Vince Young had scored low on the Wonderlic test, a written, timed test taken by draft prospects during the combine.
