Hugh Bowman has ended the season with the Sydney jockeys' premiership and a seven-meeting suspension for careless riding at Rosehill.

Bowman was outed after pleading guilty to a charge over an incident in the penultimate race on Saturday that also resulted in his mount Wild'n'Famous being relegated to second following a protest.

Leading Sydney apprentice Andrew Adkins successfully argued Most Exalted was denied victory in the ATC Thanks Our Owners Handicap (1350m) after Bowman allowed Wild'n'Famous to shift out at the 200m mark.

Most Exalted was elevated to first and then Bowman faced the stewards for a second time.

Racing NSW deputy chief steward Philip Dingwall said Bowman could resume riding on August 13, adding: "Congratulations anyway for winning the premiership."

Bowman would have missed next week's meetings regardless because he heads to Papua New Guinea on Sunday with fellow jockeys Corey Brown, Kathy O'Hara and Stephen Baster.

They will walk the Kokoda Track to raise money for the Mark Hughes Foundation for Brain Cancer Research and the National Jockeys Trust.
