The Minnesota Vikings restructured the contract of defensive tackle Kevin Williams which included voiding the final year, according to OverTheCap.com.

Per the report, the 32-year-old Williams will earn $4.9 million in 2013, a $2 million cut from the scheduled $7 million base salary he was originally set to earn. Before the restructure, Williams was due $500,000 in bonuses, but it is unclear if that has been wiped out as part of the new deal.

Williams is now scheduled to become an unrestricted free agent after the 2013 season with the last year of his eight-year deal voided as part of the restructured agreement.

There has been a steady decline in production from Williams over the last three seasons, with just a combined total of eight sacks over that time period. He averaged seven sacks a season previous to the 2010 season.

Update 12:13 PM: The workout bonus is $100,000, according to Tom Pelissero of 1500 ESPN Twin Cities. Apparently the $400,000 difference was a weight clause that has been voided. The total potential value of Williams’ deal is $5 million.
