Former Alabama Chief Justice Roy Moore, who has formed a committee to explore a possible run for president, suffered several broken ribs in a horse-riding accident at his farm near Gadsden.

Moore was injured Sunday, the same day that former Alabama Gov. Bob Riley was injured in a motorcycle crash in Alaska. Riley defeated Moore in the 2006 Republican primary for governor.

Rich Hobson, executive director of the Foundation for Moral Law, said the 64-year-old Moore fell while attempting to get on a horse. He said Moore went to an orthopedic specialist is now resting at home. Moore is president of the foundation.

Moore was removed from office as chief justice after refusing to move a Ten Commandments monument from lobby of the state judicial building.
