A mislaid lead cloth cost Brendan Powell a double at Doncaster.
Powell was first past the post in the Sky Sports Racing Sky 415 Handicap Hurdle on Eaton Hill but when he weighed in, the clerk of the scales put in an objection.
The jockey was 3lb light and he is only allowed a disparity of 1lb.
Powell weighed out with a lead cloth, but it was not there when he weighed back in after the race.
The stewards fined Eaton Hill’s trainer Kerry Lee £1,500 as the horse was not saddled with a weight cloth.
Eaton Hill had overcome a mistake at the final flight to beat Ecco comfortably, but it as all for nothing. The race was awarded to the runner-up Ecco (13-2), trained by Paul Nicholls and ridden by 3lb claimer Lorcan Williams.
Powell had won the preceding Free Daily Tips On attheraces.com Novices’ Limited Handicap Chase on Evander (5-2).
He told Sky Sports Racing: “We haven’t gone crazy and we’ve quickened up turning in between the second last and the last.
“I didn’t want to look behind and probably won a bit far in the end. He was keen early on in the race today.
“He does switch off halfway through the race, then you have to wake him up again. He’s done it pretty easy.”
One jockey who was able to celebrate a double was Tom O’Brien.
He struck on the Nick Williams-trained Prudhomme (100-30) in the Download The At The Races App Handicap Chase and followed up on Gosheven (4-1) in the Follow At The Races On Twitter Maiden Hurdle for his boss Philip Hobbs.
Of Gosheven, O’Brien said: “He’s had niggly problems, but he’s always shown a lot of promise.
“He was unlucky when brought down here at the last meeting. He got a fright but showed no ill-effects today.”
Bushypark (8-11 favourite) completed a 24-day four-timer with a dominant all-the-way win in the Visit attheraces.com Novices’ Handicap Hurdle.
Successful at Hexham just two days earlier, Phil Kirby’s in-form six-year-old ran the opposition ragged as he crossed the line two and a quarter lengths clear of the staying-on Eyeofthescorpion in the hands of 7lb claimer Joe Williamson.
