With a little more than a week to go until training camp opens, the Green Bay Packers locked up another core player for the future.

Big deals for quarterback Aaron Rodgers and outside linebacker Clay Matthews highlighted the offseason previously. Now, safety Morgan Burnett, only 24, has a four-year extension as he was preparing to enter the final season of his rookie contract.

The Packers were reportedly working on a deal for Burnett last week and they hammered it out quickly. According to Ian Rapoport of NFL.com, Burnett’s deal is worth $24.75 million and he receives a signing bonus of $8.25 million.

Burnett made 123 tackles last season with two sacks, two interceptions and two forced fumbles. The Packers also signed linebacker Brad Jones to a multi-year deal this offseason. The next big contract could be for defensive tackle B.J. Raji, who is entering the final year of his contract.
