By Steve Kim has been advised that heavyweight prospect Andy Ruiz, coming off a first round stoppage of Kenny Lemos from this past weekend in Fresno, California, will return to the ring on December 20th at the Celebrity Theater in Phoenix against veteran Sergey Liahkovich (26-6, 16KOs) on card that will be part of the 'Solo Boxeo' series on UniMas.

Ruiz, is a talented young fighter with a mark of 23-0 (17 KO's) but has struggled to keep his weight in check. Liakhovich, the one-time WBO heavyweight titlist is now 38 years old and has lost three of his last four bouts. Before defeating the pedestrian Chad Davis - who came in with a record of 5-11 - in his most recent outing, he was stopped in succession by the trio of Robert Helenius (TKO9), Bryan Jennings (TKO9) and Deontay Wilder (KO1).
