Earlier today it was reported that both WBA Middleweight champion Gennady Golovkin (30-0, 27) and his up coming opponent Marco Antonio Rubio (59-6-1, 51) have passed their 30 day weigh in.
Golovkin weighed in at just 165lbs, only 5lbs over the Middleweight weight. This proves that Golovkin really is just a small Middleweight and it also goes to show that he is always in or around his fighting weight. As for Rubio he was 174.5lbs and will need to lose 14lbs for the weigh on October 17th, the day before their fight.
For those who aren't aware of the WBC's 30 day weigh in rule it's something they have brought in to make sure fighters aren't harming themselves to make weight on the day of the weigh in. Their limit for the 30 day weigh in is 10% of fight weight, so for this Middleweight bout the 30 day limit is 176lbs.
The WBC also have a 5 day weigh in where a fighter needs to be within 5% of the divisional limit. For this bout, and all bouts at Middleweight, that rule leaves fighters with a limit of 168lbs.
As well as defending his WBA title Golovkin will be hoping to earn the WBC Silver title, that's where the WBC come in to this bout. The WBC silver title would effectively make Golovkin the mandatory for the WBC title currently held by Miguel Angel Cotto, who is also considered the "Linear" champion, or the man who beat the man. A win over Cotto would effectively put Golovkin as the divisions Kingpin and see him all but accepted as the de facto #1. As a result he has made it clear that that's the bout he really wants and that Rubio is a stepping stone to that fight.
