According to AP that Jags have informed Leonard Fournette they are going to try to void his guarantees because he was suspended for fighting against the Bills.
That would cost Fournette around $8.1 million and the Jags could cut him without suffering a salary cap hit.
Tom Coughlin went on record calling Fournette unprofessional and selfish, so it looks like they are trying to find a loophole to get out of the deal.
Once again this is one of the many reasons why NFL players CBA is trash. Fournette was fighting because his teammates were in a brawl and for that he might lose money he rightfully earned by signing his contract.
