According to Rob Demovsky of ESPN, the Packers have officially filed paperwork in an attempt to collect a portion of Martellus Bennett‘s signing bonus after they cut him loose with a failure to disclose medical condition designation.

The NFLPA tells Demovsky that they are “aware of the situation and currently monitoring.”

Green Bay paid Bennett a $6.3 million signing bonus as part of his three-year, $21 million contract. However, he managed to play seven games this season, which means it’s more likely that the Packers will target the remaining $4.2 million that’s prorated over the final two years of the deal.

Demovsky adds that the case between the Packers and Bennett will be heard by an arbitrator and need to be settled before next season because of the salary-cap ramifications.
