No, he was okay, Aldaniti. It was HARLECH CASTLE, who became wedged headfirst - one stall popped open (Frankie riding, I think), and that horse came out, then HC barged his stall, thinking racing was on, and got stuck for a good 20 minutes. The stall had to be virtually disassembled, but he came out fine and was walking around unharmed afterwards. What may have confused folks was the sight of the knacker van going down to him. Well premature, thank God.
That and subsequent races were flip starts, due to him having wrecked the stall.
