The Ring's latest divisional ratings have been released and there are changes in five different weight classes, including super middleweight.

Last weekend was a busy one for boxing in North America as three cards took place across two days.

On Friday night, the 168-pound division took centre stage as Khalil Coe won his rematch with Manuel Gallegos by sixth-round TKO in Guadalajara, Mexico. That same night, 1500 miles away, Bektemir Melikuziev won a 12-round thriller against Darius Fulghum.

Super middleweights were on deck yet again Saturday as Caleb Plant and Jermall Charlo made their returns to the ring.

Plant lost by split decision to Mexico's Jose Armando Resendiz while Charlo stopped Thomas LaManna in six rounds at Vegas' Michelob Ultra Arena. On the undercard, Yoenli Hernandez comprehensively beat Kyrone Davis.

Earlier that week, Eduardo "Sugar" Nunez became IBF junior lightweight world champion, beating Masanori Rikiishi by unanimous decision in Yokohama, Japan. Yoshiki Takei defended his WBO bantamweight title in the main event against Yuttapong Tongdee, winning by first-round TKO.
