The Rockies announced Sunday that they have moved reliever John Axford off their active roster as he deals with a family issue, replacing him with pitcher Scott Oberg, per the Denver Post.
Axford's 2-year-old son was bitten by a rattlesnake in Arizona during spring training, and complications have caused the boy to need to be flown to a specialist in Colorado. Axford, who picked up a save Thursday, will miss a minimun of three games and a maximum of seven games.
To make room for Oberg, the Rockies moved Charlie Culberson to the 60-day disabled list.
