GREEN BAY, WI (WHBL) - The Green Bay Packers have locked up the leader of their secondary after signing safety Morgan Burnett to a four-year contract worth a reported 24-and-three-quarter million dollars. The Packers did not immediately announce the deal. NFL.com said Burnett is getting an eight-and-a-quarter million dollar signing bonus, and he can get up to 26-million with incentives. He was scheduled to make almost one-and-a-third million dollars in the final year of his rookie contract. The 24 year old Burnett is entering his fourth NFL season - all with the Packers. He and Saint Louis linebacker James Laurinaitis were the only defensive players in the league not to miss a snap last season. Burnett led Green Bay in tackles with 123 last season and had two interceptions.
