Expensive colt Rathlin has ensured a place in the Magic Millions 2YO Classic with a win at Doomben in which three jockeys came to grief at the winning post.

In a four-horse Phelan Ready Stakes, Rathlin ($2.40) raced away to beat Kavak ($2.50) by three lengths with War Memorial ($4.20) five lengths away in third in the $125,000 race.

After the line three of the four runners parted ways with their their jockeys.

As the field passed the winning post, Rathlin dislodged Luke Currie with Jim Byrne (Kavak) and Larry CassidyWar Memorial) also coming off in rapid succession.

Currie and Cassidy got to their feet but Byrne was treated on the track for 20 minutes.

He was taken to hospital complaining of pain in his left leg.

It was the third fall for the day with Dale Smith being dislodged from Shono Mercy at the 800m in the fourth race.

Cassidy was also dislodged from Canapes on the way to the barriers before race six.

All three horses from the Phelan Ready were caught by track staff without apparent injury.

Stewards adjourned inquiries into the three incidents.

Rathlin was already in the Millions Classic field and his $72,000 prize money lifted him to $122,000 and second place on the ballot.

A $725,000 son of Fastnet Rock, Rathlin will give trainers Ciaron Maher and David Eustace a chance to avenge last year's second by their horse Dubious.

Kavak also ensured he would make the field with his $22,500 second prize which took him to $71,000.
