Fight Sports, the international combat sports television channel owned by New York-based CSI Sports, has secured broadcast rights to the upcoming boxing bout between Filipino legend Manny Pacquaio and Errol Spence of the USA.

Fight Sports is set to show the fight in the more than 50 countries around the world in which it has carriage deals, including Spain, Portugal, the Caribbean, the Middle East and North Africa and most of Asia.

The fight, which is due to take place in Las Vegas on 21 August, will see Pacquaio and Spence compete for the latter's WBC and IBF world welterweight titles.

However, it is in some doubt after promoter Paradigm Sports Management filed an injunction last Friday to stop the contest, claiming Pacquaio had breached a contract.

Paradigm claims to have rights to negotiate Pacquiao's next two bouts, but that the contest with Spence was done so separately.

In addition, it says it provided a $3.3 million advance to Pacquiao that has not been returned.

However, Pacquiao has filed a cross-complaint against Paradigm, alleging breach of conduct, breach of fiduciary duty and fraud among other claims.

Fight Sports, which launched in 2012, recently secured the rights to the third world heavyweight boxing title fight between Tyson Fury and Deontay Wilder, and showed the fight between US boxing superstar Floyd Mayweather and internet celebrity Logan Paul.

In addition to top boxing, its content includes prominent kickboxing and MMA fights and exclusive reality, documentary, and original programming series.
