They're both active in the Serbian league these days for some smaller clubs. Although, I'm not sure if they're still playing regularly, since I don't really follow their respective clubs.
Jovicic went to Caen after Samp but I doubt he's still there.
Another Serbian ex-Samp player and the only great out of these ones, Vladimir Jugovic, is active in the second Bundesliga these days. It's as a favour to the chairman of their club.
