Both men weighed in at exactly 130lbs on Friday ahead of their very exciting looking contest and both seemed ready to go in what could be a career defining fight for the winner.
For Salido it's a chance to claim a "world title" in a second division and take a huge step towards getting a rematch with former foe Mikey Garcia. As for Terdsak this could finally see him winning a world title havign come close in the past, notable in his bout with Takahiro Ao.
Although fighting in Mexico the officials are all from the US. The referee assigned to the bout is Eddie Claudio whilst the judges will John Madfis and the controversial due of Patricia Morse Jarman and Robert Hoyle.
For those who recognise the names of Jarman and Hoyle they have both had recent stinkers. Jarman scored the Adrien Broner/Carlos Molina bout 98-92 to Broner and also had Pungluang Sor Singyu ahead before being stopped by Tomoki Kameda. As for Hoyle he managed to give Mikey Bey 11 rounds against Miguel Vazquez.
Sadly though John Madfis is also a member of the "poor score club" having given Katsunari Takayama next to no credit for his effort against Francisco Rodrigiuez Jr, scoring that bout 119-108 for the Mexican.
Good luck Terdsak, you're really gonna need here, especially with those judges who know who know where they are this weekend.
