Joshua Clottey is expected back home tomorrow from his base in the US, where he was to begin intensive training for an upcoming world title bout against boxing sensation, Manny Pacquiao.The US Embassy in Accra refused visas to his trainer, Godwin Nii Dzanie Kotey, popularly known Alloway, and his assistant trainer Daniel Clottey.The former IBF Welterweight champion was due to begin preparations in the US ahead the March 13 bout.The refusal of visas to his trainer and assistant has raised doubts over whether the contest will come off.The trainer told Joy News the situation is very frustrating.“An officer looked into the documents that I had with me and he just wrote something that they [were] going to do their investigations…and give me a call. As matter of fact, I don’t know what investigations they want to carry out,” he told Joy Sports’ Nathaniel Attoh.Trainer Nii Dzanie Kotey said he had planned on boarding a flight on Saturday for the United States but the failure of the embassy to grant him a visa has left him rather confused.Source: Joy Sports/Myjoyonline.com/Ghana
