If Donovan (37) wins, he will win the EU super-featherweight title, which has no holder at the moment. French Samir Ziani was the last to hold the belt in 2019.
Kildare native Donovan was a highly decorated amateur on the world stage and came out of retirement in 2016 to pursue a lifetime goal of winning a World or European title as a professional.
Donovan's only defeats in his 17 fights have come against Zelpa Barrett and double Olympic gold medallist Robeisy Ramirez.
French national champion El Hadri boasts a 13-1 record.
