NEW YORK (AFP) - National Football League commissioner Roger Goodell brought down the curtain on the "Spygate" scandal here Tuesday after meeting with former New England Patriots video assistant Matt Walsh.

Goodell spoke for more than three hours with Walsh about the Patriots' videotaping coaching signals of rival teams, a violation of NFL rules, but heard no new revelations and plans no further punishment for the Patriots.

"I don't anticipate it," Goodell said. "The fundemental information provided today is consistent with what we knew last September. The punishment was implemented and I think it was appropriate."

After the Patriots were caught videotaping coaches of the New York Jets in the 2007 season opener, they were fined 250,000 dollars and stripped of their first-round selection in last month's NFL Draft.

Also, Patriots coach Bill Belichick was fined 500,000 dollars after six tapes from 2007, similar to those Walsh made from 2000 to 2002, were surrendered to Goodell by the Patriots in February.

"It was appropriate. It was unprecedented," Goodell said. "It sent a clear message to NFL clubs - play by the rules."

Walsh spoke about videotapes he made after having given the league eight tapes of signals by opposing coaches from six games in the 2000, 2001 and 2002 seasons. All were shown to reporters Tuesday.

Walsh departed the NFL offices for a meeting in Washington with US Senator Arlen Specter, who has criticized the NFL's probe and the destruction of the 2007 tapes and could push for lawmakers to look into the matter.

"Matt Walsh is pleased that he has had the opportunity to assist the NFL in its investigation regarding the Patriots' videotaping practices," Walsh lawyer Michael Levy said.

But barring any possible probe by lawmakers, the cheating scandal that has tainted the Patriots' run of three Super Bowl titles from 2002 through 2005 has run its course.

"I don't know where else I would turn," Goodell said. "I asked him that question and he said very clearly, 'I don't know anybody who would have more information.'"

The Patriots shrugged off the "Spygate" scandal and completed an undefeated season, coming within seconds of an undefeated run to a Super Bowl triumph before losing to the New York Giants last February.

Goodell said no other clubs were implicated and that he does not think such video cheating is common in the NFL.

"I think it's very limited in its practice and its effect," Goodell said. "I think teams take steps to make sure that (stolen signals tipping off schemes) doesn't happen."

Goodell and Walsh, now a golf pro in Hawaii, began talking at the league office before 8 in the morning and went far longer than expected, Walsh saying he kept the tapes for ideas because he wanted to be a coach one day.

"I told him how important it was to the league to understand all the facts and details," Goodell said. "He was responsive and I think he was well prepared."

A potential blockbuster videotape that had been reported as made - from a St. Louis Rams practice on the eve of the 2002 Super Bowl they lost to New England - was never filmed, Walsh told Goodell.

"We were able to verify there was no Rams walkthrough tape," Goodell said. "He does not know of anybody who made such a tape. He does not know anybody who knows of such a tape."

The Patriots, who had denied filming the Rams' practice, never used the tapes during the games in which the filming was done, Walsh told Goodell, saying they were in his possession the entire time.

Goodell said two possible violations unrelated to the signal stealing were uncovered - eight to 12 Super Bowl tickets re-sold for higher than printed value and a tape of an injured player practicing in violation of NFL rules.

The league is looking into the ticket issue but expects no further penalty over the practice violation.

"If we verify it, I would expect that with the fine we imposed - 750,000 dollars in total - I doubt we would take any further action," Goodell said.

Goodell said there was no other subterfuge by the Patriots.

"He was aware of no other violations by the Patriots," Goodell said. "There was no bugging of locker rooms, manipulation of communications signals, putting microphones on players to pick up opponents' signals."
