Eliminated

I watched a thrilling Olympia Grand Prix this evening on the Red Button, Bertram Allen on Quiet Easy was clear & the fastest round, but before the award ceremony he was eliminated, it would seem to be a welfare issue following his round, it wasn't clear what the issue was, eventually Michael Whitaker was awarded 1st prize
Bertram Allen is a very successful showjumper (only 20) he has successfully moved from showjumping ponies to horses & is one off the Irish showjumping stars, he looked totally bewildered.
