Racing:A host of bookmakers suspended betting on the 2000 Guineas on Monday afternoon following rumours concerning the participation of long-time ante-post favourite Teofilo.
Jim Bolger's son of Galileo is unbeaten in five starts, including two victories at the highest level.
But his price began to drift on Betfair and by 4.10pm he had been displaced at the head of the market by Peter Chapple-Hyam's Dutch Art.
Meanwhile a host of fixed-odds layers, including Guineas sponsors Stan James, suspended their markets.
By 4.50pm confidence had apparently returned on Betfair and Tefilo was again trading as clear favourite.
Coral's Simon Clare said his firm had seen a deluge of money for all the other leading fancies.
"People are coming on to back everything else in the race and in the space of 40 minutes we decided we had to pull the plug," he explained.
"In our experience, something is amiss.
"It would be a another major blow for ante-post punters who have already seen Holy Roman Emperor carted off to stud.
"When that happened, their one consolation was that Teofilo was still heading for the race, but that now looks doubtful.
"In these situations there is normally no smoke without fire and it would be the biggest double-whammy ever to punters."
