The WBC flyweight champion will not be able to defend his title on August 15th.

Due to Martinez catching a respiratory tract infection, he will not be able to fight McWilliams Arroyo in the main event that was scheduled to be in Tulsa on August 15th. This was confirmed by the World Boxing Council as Martinez (16-1, 12 KOs) will be sidelined while recovering from the illness until the end of July. He was preparing to make his 2nd defense of the WBC flyweight title after defeating Jay Harris this February in Frisco, Texas.

Martinez has been undefeated since 2015, and was briefly crowned as the WBC champion in August 2019 when his bout against Charlie Edwards was initially ruled as a win but was overturned to a no contest after it was shown that the stoppage was due to a low blow. Months later he had a second opportunity to win the title and was successful by stopping Cristofer Rosales.

Arroyo (20-4, 15 KOs) was scheduled to make his third attempt at winning a world title at flyweight. He was unsuccessful in 2014, losing a split decision to Amnat Ruenroeng for the IBF title. Almost two years later, he faced Roman Gonzalez for the WBC title but fell short by unanimous decision. He has a win over former world champion Carlos Cuadras and his been a top contender at flyweight for a while but has not captured gold as of yet.

It is unknown at the time as to if the card in Tulsa will be delayed or when Martinez would be available to fight.
