NFL Network Insider Ian Rapoport reported that the Jags are signing Jack to a four-year extension worth $57 million with $33 million in guarantees, per a source informed of the deal.
The Pro Bowls should be coming for Jack, however.
The second-round pick has become a tackling machine in the middle of the Jags defense, compiling 197 tackles the past two seasons with 4.5 sacks, four passes defended and one INT. He hasn't missed a game in his three-year career despite entering the league with questions about his knee coming out of UCLA.
The 23-year-old linebacker continues to be a rising player and plays a pivotal, physical role in the middle of a Jaguars defense that appears set for a bounce-back campaign in 2019.
Jack was set to play out the final year of his rookie deal with a base salary of $1.314 million. Now the linebacker has a hefty payday coming his way.
