A former Florida State standout, Jernigan, 25, would have been eligible to test free agency in 2018.
While investing an insain $151 million in the defensive tackle position over the next six years is an incredibly had pill to swollow, the Eagles have without a doubt one of the best defensive tackle duos in the nation and have locked them up for the next four years. So he's now signed through 2021. Jernigan, a 25-year-old Florida State product, adapted nearly instantly to defensive coordinator Jim Schwartz's attack scheme after being acquired from the Baltimore Ravens in the offseason.
The Eagles had about $6.3 million available under their 2017 adjusted salary cap figure of just under $175 million. The Eagles are an NFL-best 8-1.
More importantly, the Eagles are allowing just 66 rushing yards per game and no running back has cracked the 100-yard mark against them. He also has 1.5 sacks and five hurries. The 7-2 Eagles head into Week 10 with the league's top-ranked run defense. More than $62 million in guarantees is now earmarked for two players on the interior of the defensive line.
The deal is worth $48 million, including $26 million guaranteed, according to ESPN.
More than one quarter of the team's roster is comprised of Eagles who are in the past year of their deals, so Roseman will need his best number-crunching this offseason.
Destiny Vaeao still has a year left on his deal at $632,000 while Elijah Qualls is under control through 2020 after signing his rookie contract during he offseason.
