PITTSBURGH — The agent of Pittsburgh Steelers linebacker James Harrison says the player's young son is "doing well" at a Pittsburgh hospital following an attack by a pit bull.

Agent William Parise says 2-year-old James Harrison III was bitten on the thigh after his mother let the dog out of its pen Thursday afternoon. Parise said Saturday he was with the boy at UPMC Children's Hospital of Pittsburgh, and the boy was expected to remain there for another day or two.

Parise says the woman and the player's massage therapist also were hurt trying to help the boy, and the therapist needed three stitches.

A hospital spokesman declined comment Saturday, saying the family has asked that no information be released.
