The NFL has suspended free agent Jason Ferguson for the first eight games of next season for violating league policy on performance-enhancing substances.

NFL spokesman Greg Aiello confirmed the nose tackle's suspension Sunday, but said he could offer no further details.
Ferguson is a free agent who sat out the latter part of last season with the Miami Dolphins with a quadriceps injury and underwent surgery in December.
The 35-year-old had been in on 23 tackles in nine games for the Dolphins last season.
Dolphins spokesman Harvey Greene says the team has no comment since Ferguson isn't officially on their roster.
Oddsmakers from online sports book SPORTSBETTING.com have made the Dolphins 40/1 long shots to win the 2011 Super Bowl.
