Scott Fujita (now with the Browns) and Anthony Hargrove (now with the Packers) were handed three- and eight- game suspensions, while current Saints defensive end Will Smith was docked the first four games of the season.
ESPN's Adam Schefter tweeted that the four players plan on appealing the punishments, quoting a source saying "Get ready for a massive multiple legal battle over this on several fronts." He also reported on SportsCenter that the players are expected to take their case to federal court instead of the usual appeals process with the league office (Via ProFootballTalk).
Judging from the reactions of players around the league, it seems most will (not surprisingly) be on the side of the players. Scroll down to see how the league responded to the Saints suspensions.
