Keravnos fought like lions but fell away over the last four minutes and lost heavily in the EuroChallenge to Ural Great 85-64.
Jumaine Jones drilled four of six shots from long range and finished with 21 points for the winners in Perm, Russia, as they improved to 2-1.
Cyprus outfit Keravnos, who slipped to 0-3, were led by LaMarr Greer's game-high 27 points.

However, Jones replied with a three-pointer to spark an 11-1 run that was capped by a Ralph Biggs dunk for Ural Great.
Keravnos continued to battle with a Greer three trimming the deficit to 57-49, only for Jones to take his points haul to eight with a jump shot at the end of the quarter for a lead of 10.
Jones then poured in the first five points of the fourth quarter to extend the advantage to 64-49.
An Aleksandar Damjanovic jumper would end up cutting the deficit to 72-61 with 4:07 to go, but that was as close as Keravnos would get.

Vasilis Fragias, Coach of Keravnos:
"Today the host team was stronger than us, especially in the last quarter. In our team I would like to thank LaMarr Greer who had an excellent evening. Keravnos is a young team.
