The Colorado Rockies have placed John Axford on the family medical emergency list, allowing the right-hander to tend to his young son, who was bitten by a rattlesnake last month in Arizona.

Axford said his son had surgery Monday on his right foot to remove necrotic tissue. Axford said the toes of 2-year-old Jameson "look fine," but doctors are trying to improve mobility as they combat infection.

Jameson will board an emergency medical flight Monday to Denver for more treatment.

"We still have a long road, a long process to go," Axford said. "But at least I'll be able to be closer to him."

Axford will be out at least three days and a maximum of a week.
