Police: Miguel Cotto, uncle trade blows

SAN JUAN, Puerto Rico -- Puerto Rican police say they are investigating an alleged fight between WBO welterweight champion Miguel Cotto and his trainer, who have had a sometimes combative relationship in the past.

A statement issued by the police says the elite boxer and Evangelista Cotto, the fighter's uncle, exchanged blows Wednesday after a heated argument about training at a gym in the champ's hometown of Caguas.

After the bruising scrap, Evangelista Cotto allegedly threw a cement block on his nephew's 2009 Jaguar, shattering a right-side window.

Cotto's spokeswoman did not immediately return calls seeking comment.

Puerto Rican detectives are investigating the incident even though neither of the men has filed a complaint.
