Glasgow Sheriff Court heard the 35-year-old would lose his boxing licence if he was remanded in custody.
Harrison appeared in court on December 31, charged with forcing his way into a property on Aikenhead Road, Glasgow, shouting, swearing, damaging a TV and scaring his ex-girlfriend, Stacey Gardner.
The alleged incident happened on December 30 and the boxer pled not guilty the following day and a trial date was set for later this year.
He was granted bail with the special conditions not to enter the house at Aikenhead Road and not to approach or contact Miss Gardner.
Harrison, whose address was given as Vicarland Road, Cambuslang, appeared from custody at the same court charged with breaching his bail conditions, 24 hours after they were imposed.
He is alleged to have been at the same party as Miss Gardner on January 1, at a mutual friend's house.
The professional fighter is also charged with behaving in a threatening or abusive manner at the house at Ritz Place, Glasgow, and at Cathcart police office.
It is alleged he behaved in a threatening or abusive manner by repeatedly shouting, refusing to leave and making threats of violence towards Miss Gardner.
The Crown opposed bail but the defence told the court: "He has a large amount to lose if he does not get bail."
It was claimed he would lose his boxing licence if he were remanded in custody and that he had a professional fight later this month.
Sheriff Linda Ruxton told Harrison: "On balance I have decided to release you on bail pending your trial."
She added that it was "with some hesitation".
