Jones attended a polo match in Houston on Sunday, just two days after a fall from his horse that landed him in the hospital.
Jones showed up at the Houston Polo Club to watch his team from the sidelines. The actor says Friday's accident at another polo field happened when his horse stumbled. The actor was knocked unconscious and spent the night at Houston's Hermann Hospital.
The actor was launched over the horse's head and the horse stepped on him at the Estancia Del Pueblo Viego, a private polo ranch about 45 miles west of Houston in Sealy.
Jones was relaxing after completing work on the Paramount film Double Jeopardy last weekend, Allen said.
Jones won an Oscar for best supporting actor for his role as a federal marshall in the 1993 film The Fugitive. He won an Emmy for his 1982 portrayal of killer Gary Gilmore in the made-for-televison movie The Executioner's Song.
His other films include Men in Black, Natural Born Killers, and The Client.
