The woman who was violently beaten by Zac Stacy is set to testify in court against the ex-NFL player on Wednesday ... hoping a judge makes it harder for Stacy to be released from custody.
Kristin Evans will be in the Orange County, Fla. courtroom in just minutes ... arguing that Stacy's bond should be heavily increased.
A judge initially set the bond at $10,150 for Stacy -- who was charged with two felonies over the Nov. 16 attack on Evans -- but Evans argued on social media afterward that was nowhere near enough.
