(Reuters) - Welterweight champion Errol Spence, Jr. has been forced to withdraw from his Aug. 21 fight against Manny Pacquiao due to a retinal tear in his left eye, organisers said on Tuesday.

Cuban Yordenis Ugas, who won a bronze medal at the 2008 Beijing Olympics, has agreed to replace Spence in the main event at T-Mobile Arena in Las Vegas and defend his WBA welterweight belt against Pacquiao, who has won titles in eight divisions.
