Jono Carroll will face former European champion Guillaume Frenois in a final eliminator to become mandatory challenger for the IBF Super-Featherweight title.
The unbeaten Dublin boxer recently signed with Matchroom and will challenge for the number one spot for the belt that James Tennyson came up short for against champion Tevin Farmer last month in Boston.
Carroll knocked out Declan Geraghty in Belfast in June and then joined Eddie Hearn's stable. He currently holds the IBF Intercontinental belt, with eyes now turning to the world strap.
Cork middleweight Gary 'Spike' O'Sullivan was included on the card on 8 December, despite being announced for the Ray Moylette show the previous day last Friday.
RTÉ Sport understands he will fight in Mayo and not feature in Sheffield.

The card takes place in Sheffield as Kell Brook headlines against Michael Zerafa in the Sheffield Arena.
