I watched the replay this morning.
What a mess.
Looked like the 8 and 9 interfered with eack other going to the gate.
Starter calls a recall and you can hear announcer call recall.
Starter closes the gate and speeds off as normal.
Two horses keep going as normal race.
Some start to pull up then rethink and take off to catch up.
Announcer calls the race as if everything is ok.
Winner goes back to winners circle.
Long delay then No Contest.
IMHO
It was the starters fault for closing the wings and speeding off
