Speaking after a voluntary practice Monday, Whitner added he is confident charges against him could be dropped as early as Tuesday, when he is scheduled to appear in Cleveland Municipal Court.
"I can assure everyone that I didn't do anything wrong," Whitner said. "Hopefully, we're going to get it all figured out. We expect it to be dropped, and hopefully it's dropped tomorrow."
Without going into detail, he added his attorney has received a videotape of what happened when police used a stun gun and handcuffed Whitner after he tried to force his way past officers trying to control a crowd outside a nightclub on April 11.
Whitner was charged with aggravated disorderly conduct and resisting arrest.
It was unclear why Whitner tried to leave the club and head for the melee. According to a police report, he told officers, "My cousin's out there, and they've got guns."
Andrea Taylor, a spokeswoman for the city of Cleveland, said it is city policy not to comment on pending cases.
Whitner's attorney did not return a message seeking comment.
Whitner has previously said he regrets what happened. On Monday, he added he intends to tell his side of the story after it's settled in court.
"I don't have any grudges against anybody, but people will try to pick it up and take it and turn it without getting both sides of the story," Whitner said. "That's the only frustrating part about it, is one side of the story gets put in there when a lot of stuff is totally false."
Whitner is one of four Bills players to have had run-ins with the law this offseason. It's a group that includes starting running back Marshawn Lynch, who was suspended for three games by the NFL after he pleaded guilty in March to a misdemeanor gun charge in Los Angeles in March. Lynch is appealing the NFL suspension.
Last week, Bills fullback Corey McIntyre was arrested in Florida, where he was accused of fondling himself outside a woman's home. McIntyre's agent, Brad Tessler, says his client is "guilty of absolutely nothing" and looks forward to proving the accusations false.
McIntyre is free on $10,000 bond, but did not attend the Bills practice on Monday.
