The World Boxing Association bantamweight 118 lbs Champion, Briton Jamie McDonnell and his challenger, Japanese Tomoki Kameda met at the weigh-in at the State Farm Arena in Hidalgo, Texas.
Both fighters weighed 117.8 pounds on the scale.
McDonnell (25-2-1, 12 KO) is defending his title for the second time which he won on May 31 2014 when he defeated Tabtimdaeng Na Rachawat by TKO 1 in London.
The Challenger is the former WBO champion, the youngest of the Kameda dynasty (31-0, 19 KO) and is making his first attempt for the WBA belt.
Luis Pabón will be the referee, and Ignacio Robles (PAN), Lynn Carter (US) and Nelson Vasquez (PUR), as judges, all of them under the supervision of Carlos Chávez (VEN).
Editor’s note: Also on the bill, Omar Figueroa came in just over the 140lb limit for his clash with Ricky Burns, although the fight still goes ahead, whilst former WBA champion Austin Trout and Luis Galarza made their contracted 157lb limit.
