NFL offensive lineman Chad Wheeler has pleaded not guilty to 3 criminal charges ... this just days after he was accused of violently beating his girlfriend.
The 27-year-old showed up to a court room in King County, Wash., on Monday to enter the pleas, according to ESPN.
He was then ordered to stay in the state of Washington and to remain under electronic home detention with a monitoring device strapped around his ankle.
Wheeler -- under the conditions of his pretrial release -- had already been ordered to have zero contact with the alleged victim.
