Melbourne Cup favourite Constantinople to be ridden by Glen Boss after Nolen axe

Jockey Luke Nolen has been replaced on Melbourne Cup favourite Constantinople by Everest-winning jockey Glen Boss.

Nolen, who enjoyed an unblemished 22-win record aboard champion sprinting mare Black Caviar between 2009 and 2013, had a luckless passage aboard Constantinople in Saturday’s $5m Stella Artois Caulfield Cup.

Constantinople was the first northern hemisphere three-year-old to run in the Caulfield Cup and finished an eyecatching fourth after breaking slowly and then finding interference approaching the home turn and early in the straight.

"He was terrific," Nolen said post-race. "It was a muddling race and with a big-striding horse that was probably against us from an inside draw. We can look at the silver lining, he doesn’t get a penalty for the Melbourne Cup and Flemington will suit."

It is understood the decision to part company with Nolen and use Boss came from the ownership group. Coolmore retained a quarter-share in Constantinople when the colt was transferred from Aidan O’Brien to Lindsay Park Racing.

Boss, who guided the Coolmore part-owned three-year-old colt Yes Yes Yes to victory in Saturday’s $14m Everest at Randwick, has also ridden many horses for Constantinople’s part-owner Scott Perrin.

Constantinople will carry 52.5kg in the Melbourne Cup and Boss will have no trouble making the weight.

Tom Dabernig, who trains Constantinople in partnership with David and Ben Hayes, described his Caulfield Cup effort as "brilliant". "I think he'll be a lot more suited with the bigger track at Flemington,” he said.

"We bought him as a Melbourne Cup horse. Pulling up he wouldn't have blown a candle out. He's still a big baby, he's only three and he'll get better with racing."
