The NFL Players Association filed a grievance saying the New England Patriots should turn over $82,000 of unpaid and owed money to former player Aaron Hernandez for his participation in the club's offseason working programs from April to June 2013.

Hernandez's contract stated that he would receive the specified amount if he participated in 90 percent of the team's voluntary offseason workouts, according to The Associated Press.

The NFLPA issued the following statement regarding their filed complaint:

"On behalf of all players, it is our responsibility to protect the rights in the collective bargaining agreement. We are not tone-deaf to what the allegations are in this case, but for the benefit of all players, there are important precedents here we must protect."

It has not been confirmed whether Hernandez's fiancée, Shayanna Jenkins, will receive any of the $82,000 in the form of child support for their son.

Hernandez was released by the Patriots on June 26, the same day he was arrested in connection with the murder of his friend Odin Lloyd. The late, semi-professional football player from Boston was dating Jenkins' sister.

Hernandez was charged with first-degree murder as well as five gun-related charges. The former tight-end was indicted by a grand jury on a first-degree murder charge lon Aug. 22. He pleaded not guilty and is being held without bail at a county jail.

It was revealed earlier in August that Jenkins was being investigated by authorities in the search for the murder weapon. Authorities searched a storage unit registered to her because they believe she made "overt attempts to hide evidence ... and to hinder and mislead" investigators., according to court documents obtained by The Hartford Courant.
