New Orleans Saints linebacker Jonathan Vilma was suspended without pay for the entire 2012 season by the NFL, one of four players punished Wednesday for participating in the team's cash-for-hits bounty system. Defensive lineman Anthony Hargrove, now with the Green Bay Packers, was suspended for the first half of the 16-game season; Saints defensive end Will Smith was barred for the opening four games; and linebacker Scott Fujita, now with the Cleveland Browns, will miss the first three games. Like Vilma, they were suspended without pay. All four players have three days to appeal NFL Commissioner Roger Goodell's ruling, and the head of the NFL Players Association said the union would fight the penalties. Fujita is a member of the NFLPA's executive committee. The league's statement said Vilma, Hargrove, Smith and Fujita were suspended because of "conduct detrimental to the NFL as a result of their leadership roles" with the bounties. Goodell has made an effort to emphasize player safety in recent seasons. The NFL is facing dozens of lawsuits brought by more than 1,000 former players who say the league didn't do enough to warn them about - or protect them from - the dangers of concussions. In March, Goodell suspended Saints head coach Sean Payton for all of next season, and levied other penalties against the club.

Originally, the league said that 22 to 27 defensive players were involved in the illegal scheme, which was orchestrated by then-Saints defensive coordinator Gregg Williams and started in the season New Orleans won its only Super Bowl championship. Targeted opponents included quarterbacks Aaron Rodgers, Cam Newton, Brett Favre and Kurt Warner. "Knockouts" were worth $1,500 and "cart-offs" $1,000, with payments doubled or tripled for the playoffs. "In assessing player discipline, I focused on players who were in leadership positions at the Saints; contributed a particularly large sum of money toward the program; specifically contributed to a bounty on an opposing player; demonstrated a clear intent to participate in a program that potentially injured opposing players; sought rewards for doing so; and/or obstructed the 2010 investigation," Goodell said in a statement. While the league said that its investigation showed "a significant number of players participated" in the bounties - by ponying up cash or collecting it - "the players disciplined participated at a different and more significant level." According to the league, Saints defensive captain Vilma offered $10,000 in cash to any player who knocked then-Cardinals QB Warner out of a playoff game at the end of the 2009 season, and the same amount for knocking then-Vikings QB Favre out of that season's NFC championship game. The Saints were flagged for roughing Favre twice in that game, and the league later said they should have received another penalty for a brutal high-low hit from Remi Ayodele and Bobby McCray that hurt Favre's ankle. He was able to finish the game, but the Saints won in overtime en route to the NFL title. According to the NFL, Fujita "pledged a significant amount of money to the prohibited pay-for-performance/bounty pool during the 2009 NFL Playoffs when he played for the Saints."
