Michael Vick is free on bond after entering a not guilty plea to dogfighting charges in federal court.
Vick and three others entered their pleas to conspiracy charges involving competitive dogfighting and training pit bulls for fighting.
The four defendants had to surrender their passports and were ordered not to travel outside their immediate area without court approval.
Vick was booed by a crowd of hundreds as he arrived at the courthouse.
He faces up to six years in prison if convicted.
Meanwhile, the Falcons opened training camp on July 26,, but the NFL commissioner has barred Vick from attending while the league investigates the charges against him.
