Philadelphia school district officials say a high school football player has died of a drug-resistant staph infection.

The officials say tests on Friday confirmed that 17-year-old Saalen Jones had the contagious germ known as MRSA (MUHR-suh).

District spokesman Fernando Gallard says two other players have lesions that are being tested for the MRSA bacteria and the school is being cleaned.

Jones was a senior at Philadelphia's Martin Luther King High School. He died Tuesday.

In recent years, MRSA has become more common in hospitals, prisons, gyms and locker rooms, and in poor urban neighborhoods.
