Newcastle United have confirmed that defender Lubomir Satka will leave the club to join Slovakian side DAC Dunajska Streda.
The 21-year-old, whose Magpies contract runs out at the end of June, is to join the Fortuna Liga outfit on a three-year deal with the option of a further year.
Satka arrived at St James' Park from FK Dubnica in 2012, and progressed through the ranks before making his first-team debut in an FA Cup tie at Leicester City in January 2015.
Despite being compared to Fabricio Coloccini by former manager Alan Pardew and taking the captain's armband in the reserves, he did not add to his solitary first-team appearance for Newcastle.
The Slovakian centre-half also spent time out on loan at then-League Two side York City, as well as enjoying a successful stint with DAC during the second half of last season.
