Kansas City Chiefs veteran defensive end Tyson Jackson reduced his scheduled base salary for this year from $8.05 million to $4.25 million, a league source confirmed.
Of that figure, $4 million is fully guaranteed for skill, injury and cap.
The former first-round draft pick from LSU can make another $500,000 in 2012 through playing-time incentives.
A previously scheduled year of the deal, the 2014 season, has been deleted.
Jackson had hit an escalator clause boosting his base salary from $2.505 million to $8.05 million with his 2013 base salary up to a hefty $14.72 million from an original $3.22 million level.
Just part of the $14.72 million is guaranteed for injury and salary cap: $3.22 million.
