One is 18-year old Kenan Smajlovic who was apparently with Iowa Rush SC and the other is 20-year old Mirza Karasalihović who was with Littleton SC. Both signed with Teplice nad Vahom over the winter break and have played in 2 games since the season has restarted. The Slovak FA lists them as American. http://sfz.futbalnet.sk/zapas/154026/ (just click on their names for the profiles) I believe both are of Bosnian heritage, and I have no idea what their status is with B&H.
