Reds pitcher Bronson Arroyo has been tested for a fungal infection in his lungs.
The right-hander has been sick for more than 10 days with flulike symptoms.
Cincinnati said Friday that he's gotten blood tests and chest X-rays to see if he has valley fever, a fungal infection found in desert regions of the Southwest. The fungus is released from the soil and inhaled.
The disease is treated with rest and drugs.
