Randox Health Grand National winner One For Arthur has been ruled out for the season, trainer Lucinda Russell has revealed.
This year's Aintree hero is suffering with a tendon problem in his right fore and will not attempt to repeat his famous Aintree success next April.
Russell said: "He's out for the season. It's not a big injury, but it's enough for us to stop with him. It's obviously a shame, but hopefully we can get him back to full fitness."
