Payments were made for plays such as interceptions or fumble recoveries. All such payments are against league rules. Payments also were made for plays on which opposing players were injured. In addition, specific players were sometimes targeted. The investigation showed bounties being placed on four quarterbacks of opposing teams - Brett Favre, Cam Newton, Aaron Rodgers, and Kurt Warner. Multiple sources have confirmed that several players pledged funds toward bounties on specific opposing players, with defensive captain Jonathan Vilma offering $10,000 to any player who knocked Brett Favre out of the NFC Championship Game in 2010.
