The team has agreed on a five-year contract extension through 2022 with guard Gabe Jackson worth $56 million, a source informed told NFL Network Insider Ian Rapoport on Thursday. The team later made the announcement official.
The 25-year-old lineman started 28 games over his first two seasons at left guard. He switched to right guard after Osemele signed with the Silver and Black last offseason, and didn't skip a beat. Jackson didn't allow a single sack in the 2016 campaign, and was named as a Pro Bowl alternate.
With two members of that vaunted 2014 draft class staying for the long haul, all eyes will shift to Mack as the next in line to collect a big payday. Given the team's current cap situation, Rapoport reported that the Raiders will focus on a new deal in 2018 for the superstar pass rusher.
