SAN JUAN, Puerto Rico — Former champion boxer Hector “Macho” Camacho was seriously wounded Tuesday in a shooting outside the Puerto Rican capital, and doctors and his spokesman said he was expected to survive.

At least one gunman opened fire on the 50-year-old Camacho and another man as they sat in a car in the city of Bayamon. The other man, whose relationship to the former boxer wasn’t immediately known, was killed, according to a statement from police.
