The alleged incident took place in April 2010 while the Jets' third-round draft pick was a student at Hampton University. The criminal trial is scheduled to begin May 22.
People close to Ellis said the alleged victim harassed his girlfriend and came at the player with a baseball bat, and the tackle acted in self-defense, according to ESPN New York. Ellis' trial has been postponed twice.
Ellis also is facing a civil suit in relation to the incident, in which Dennis Eley, who's seeking $3 million in damages, accuses Ellis of breaking his nose and jaw, which required two surgeries.
Ellis is due in Hampton, Va., on Thursday for a pre-trial hearing. Because of Ellis' "permanent resident" status, if he is convicted of an aggravated felony, he could be deported. Ellis is a native of Jamaica who moved to Florida at the age of 11.
Ellis appeared in five games for the Jets last season and started in two.
