European cruiserweight titleholder Leonardo Mosquea and mandatory challenger Mateusz Masternak were able to avoid a purse bid when they reached a deal to face one another before today's deadline.

The two will collide in Zakopane, Poland on a show promoted by Knockout Promotions on October 4.

Mosquea claimed the vacant EBU title when he upset former British champion Cheavon Clarke as part of Matchroom's Monte-Carlo show on December 14. The veteran challenger, who has since boxed for world honours, previously held the same title in 2012.

The Ring's No. 8-rated cruiserweight contender Mosquea (17-0, 10 KOs) was born in the Dominican Republic before basing himself out of France, where he made his professional debut in 2019.

A first-round knockout over Brice Clavier saw him win the vacant French title in March 2023 before venturing onto the European scene last year. Mosquea, 31, has outpointed Dylan Bregeon, Clarke over 12 rounds and most recently inflicted a ninth-round stoppage on Argentina's Ivan Gabriel Garcia during a stay-busy assignment in June.

Masternak (49-6, 32 KOs) by contrast, has been a professional since 2006. The Polish fighter won his first 30 fights and claimed the aforementioned European title, but lost it in a 11th-round stoppage defeat by future WBC titleholder Grigory Drozd.

Afterwards, he came unstuck in 12-round losses to Youri Kalenga and another future cruiserweight champion in Tony Bellew.

However, he bested former unified cruiserweight kingpin Jean-Marc Mormeck in a 10-round split decision before stopping Kalenga after six rounds of their rematch. A narrow competitive defeat by former two-time champion Yuniel Dorticos saw him exit the World Boxing Super Series in the opening round, back during the division's 2018-19 season.

The 38-year-old contender rebounded with six consecutive victories to earn a shot at then-WBO titleholder Chris Billam-Smith. Although he was leading on two of the scorecards after seven rounds, he was stopped with a broken rib in the eighth. The 38-year-old has since returned with two victories in 2024 - most recently a points nod over Floyd Masson.
