Burress, who accidentally shot himself Friday night in the right thigh at a Manhattan nightclub, did not enter a plea, though his attorney said Burress planned to plead not guilty.
A grand jury will hear evidence and make a decision on whether Burress will be indicted. Illegal possession of a firearm carries a mandatory minimum sentence of 3½ years. Burress could face up to seven years in prison if convicted on a felony charge of carrying a concealed weapon without a permit.
According to ESPN.com:
A more detailed timeline of the evening also emerged. Police said Pierce, Burress and running back Derrick Ward arrived at the club with two other people around 11:30 p.m. Friday.
Burress had been allowed to bypass security, even though they knew he was armed, according to a law enforcement official who spoke with The Associated Press on condition of anonymity. The club is said to be fully cooperating in the investigation.
Around 12:05 a.m., as Burress was being escorted to a VIP area with a drink in one hand, he somehow ended up fumbling his gun and it discharged, hitting his thigh. Pierce was with him when that occurred, police said.
