Kuper is scheduled to make a base-guaranteed salary of $1.05 million this season, as part of an injury-protection settlement, regardless of how many games the veteran guard plays.
Where the change comes is in the amount of money he can make in playing-time incentives. According to NFL.com's Ian Rapoport, Kuper can make as much as $2.8 million and as little as a total of $1.1 million based on how many games he plays.
The modifications to Kuper's contract already have been agreed to, and the deal should be signed today, per Rapoport.
