Hernandez is being held without bail in a Bristol County, Mass. jail while he awaits trial on a first-degree murder charge, as well as multiple weapons violations. The Patriots released the tight end in June, just hours before the murder charge was announced.
The non-injury grievances were filed this week by the NFLPA, Breer reported. In total, they seek $6.21 million that the union believes the Patriots already owe or will owe Hernandez, according to Breer.
In one grievance, the NFLPA said the Patriots failed to pay the $1.323 million guaranteed in Hernandez's contract for 2013. The grievance also "anticipates" the Patriots withholding the $1.137 million guaranteed in Hernandez's 2014 salary and $500,000 guaranteed in his 2014 workout bonus.
The second grievance stated the union anticipates the Patriots also withholding $3.25 million in deferred signing bonus money, which will be due to Hernandez on March 31, 2014.
