O’Brien jnr out of Arc contention

Joseph O’Brien will not ride Camelot if this season’s Epsom Derby winner runs in the Prix de l’Arc de Triomphe next Sunday.

O’Brien has partnered the four-times Group One scorer, trained by his father, Aidan, on all five starts to date but is unable to make the weight for Europe’s premier mile-and-a-half contest at Longchamp.

Aidan O’Brien said: “Bar we cut off one of his arms, he (Joseph) will not be on Camelot.
