Stadthalle, Rostock, Mecklenburg-Vorpommern, Germany - Size matters. Moving up two weight divisions for a fight for the WBO Youth super middleweight crown, Italy-based Romanian prospect Gheorghe "Jon Jon" Sabau was out of his league against defending champion Tyron Zeuge, who secured the victory with several knockdowns on pace to a ninth round TKO. The second successful defense for Zeuge (13-0, 7 KOs), and the first professional loss for Sabau (10-1, 6 KOs).

IBF #1 and WBO #7 heavyweight Kubrat Pulev (20-0, 11 KOs) shook off some ring rust, easily dispatching Croatian journeyman and an ultra-late sub Ivica Perkovic (20-24, 15 KOs) in three rounds. Perkovic retired for good in his corner during a break between the third and the fourth rounds. Perkovic was picked as a last-minute opponent after no less than four previously scheduled Pulev's opponents failed to take part in this tune-up contest.

WBA #9 light middleweight Jack Culcay-Keth (17-1, 10 KOs), once an amateur world champion in Milano in 2009, continued to steady rise in ranks with a convincing unanimous decision over former world-title challenger Salim Larbi (19-5-2, 7 KOs). Culcay won 117-111 on all the judges' scorecards to retain his WBA I/C title.
