Two men were bitten by rattlesnakes in separate incidents Sunday. 

The first incident happened around 8:30 a.m. near Cortaro and Interstate 10 when 23-year-old man riding his mountain bike in the desert was bitten by a snake in the calf, Capt. Adam Goldberg, a Northwest fire spokesman said in a news release. 

Shortly before noon, a 68-year-old man working in his backyard near Camino de Oeste and Ironwood Hill Drive, was wearing flip flops and bitten by a snake on his big toe, the release said. 

Both men were taken to the hospital for treatment and were in stable condition.
