The New York Giants have refused to pay suspended receiver Plaxico Burress a $1 million portion of a signing bonus from a contract signed in September.

NFL Players Association union spokesman Carl Francis confirmed last night that the team decided to not make the payment, which was due yesterday.

On Tuesday, the union filed a grievance challenging the Giants' decision to suspend and fine Burress last week after the Super Bowl hero accidentally shot himself in a Manhattan nightclub Nov. 29.
