New Zealand trainer Jeff Lynds is waiting on blood test result s taken from Wall Street after the star galloper suffered from a bout of colic on Wednesday.

A bad result is more than likely to see the five time Group 1 winner miss the 2011 Group 1 $1m Mackinnon Stakes (2000m) at Flemington.

Colic is a common ailment that can strike in the blink of an eye and a bout can vary in severity.

Wall Street is rated a $12 chance with Luxbet and $13 with Tabsportsbet for the Mackinnon.

The blood tests results will be known this afternoon.
