The Bills have addressed the contracts of both their centers.

Field Yates of ESPN.com reports that the team has restructured the contract of starter Eric Wood. He converted $3.775 million of his $4.775 million base salary for the 2016 season into a bonus. They also added a voidable year in 2018 to his deal, allowing the Bills to reclaim about $2.5 million in cap space this year.

Yates reports that the team also extended the contract of backup Patrick Lewis through the 2017 season. Lewis, who was claimed off of waivers from the Seahawks, was due to make $1.671 million this year. His salary for 2016 has dropped to $800,000 to go with a $200,000 signing bonus. He stands to make a non-guaranteed base salary of $1.2 million in 2017.

Right tackle Jordan Mills is the only starting Bills offensive lineman that is not signed through at least the 2017 season.
