Brandon Graham will have a shot at earning even more money than he originally signed for over the next two seasons.

The Eagles have added $1.5 million in incentives to the final two years of Graham's contract, a league source confirmed to CSNPhilly.com's Reuben Frank on Wednesday. 

ESPN.com's Field Yates was first to report the news and details of Graham's revised deal. Currently in the third year of a four-year, $26 million deal, the 29-year-old defensive end is set to earn a base salary of $6.5 million over the next two seasons. 

Graham can earn up to $500,000 more in incentives this season — based on sack total and Pro Bowl/All-NFL team selection — and $1 million more in 2018, per Yates' report. Graham's performance in 2017 will dictate how much more his base salary increases in 2018.

If Graham records seven or eight sacks in 2017, his base salary in 2018 will increase by $250,000. If his sack total falls between nine and 11, his base salary increases by $500,000. Finally, if he records 12 or more sacks, his base salary increases by $750,000. His career-high for sacks is 6½, set in 2015.

In addition, Graham's base salary will increase by $250,000 if he is voted into the Pro Bowl on the original ballot or is named to an All-NFL team.

In 2016, his first season starting all 16 games, Graham had 5½ sacks and 59 tackles en route to being named second-team All-Pro. He has yet to make the Pro Bowl.
