Connections of the mighty Black Caviar are preparing to make an announcement on the suitor of Black Caviar tomorrow but it appears the lucky stallion is Exceed And Excel.

Social media went into a frenzy last night, suggesting that Darley's Exceed And Excel had been chosen and many subsequent stories have been written but managing part-owner Neil Werrett remained tight lipped when asked if it was confirmed.

"No official announcement until Wednesday," he said.

Exceed And Excel is set to be crowned Australia's champion sire thanks to a magnificent season that netted over $11.2 million in prizemoney.

His juveniles dominated the Sydney autumn carnival with Overreach winning the Golden Slipper (1200m) and Guelph taking out the two remaining legs of the Triple Crown - the Sires' Produce Stakes (1400m) and Champagne Stakes (1600m).

Exceed And Excel currently stands at Darley's Kelvinside in the NSW Hunter Valley for a fee of $88,000. (
