Boxer Prichard Colon was in critical condition Sunday after suffering a brain bleed from an injury during a bout in northern Virginia, an official said. Colon underwent surgery to relieve pressure on his brain after his bout Saturday afternoon against Terrel Williams in the Washington, D.C., suburb of Fairfax, Virginia, said Lou DiBella, president of DiBella Entertainment.
