Simon Told Helen has been scratched from the Group 1 National Derby at Wentworth Park on Friday night.

The David Burnett trained chaser was the $2.10 favourite with TAB in front of fellow Victorian Hard Style Rico.

“Sometime during the last week, Simon Told Helen was bitten by a spider on his right back leg,” trainer David Burnett said.

“The wound is healing very well and he is feeling terrific but the owners and myself wish to allow him plenty of time to recover to 100 percent.”
