Von Miller is finally opening up on his domestic violence arrest ... adamantly saying the allegations against him are "100 percent false."
The Buffalo Bills superstar sat in front of media members for over 10 minutes on Thursday to explain his side of the story ... roughly one month after he was thrown behind bars for allegedly roughing up his pregnant girlfriend during a bye-week argument in Dallas.
Miller repeated over and over again that he did not put his hands on his GF -- saying emphatically, "All of it is incorrect. All of it is untrue."
"Never in any of my relationships that I've been in, never in my current relationship with my girlfriend, did any of those things happen," he said.
"It is 100 percent false," he added. "It's overblown."
Miller was accused of pushing and shoving his GF, before putting his hands around her neck following a dispute over travel plans. In 911 audio, Miller's alleged victim can be heard telling an operator, "My boyfriend was choking me, hitting me, pulling my hair."
"I have bruises all over me," she added in the call, before saying she had "some blood on me."
Miller, however, said the claims were simply just not true, telling reporters, "All of it is incorrect."
"All I can say is it's just a matter of time before everything gets set straight," he said.
