Versatile Irish campaigner She's Our Mare will not bid for another big British prize in the Worthington Lincoln a fortnight on Saturday.
The Tony Martin-trained seven-year-old was not among 104 acceptors for the #50,000-added Doncaster handicap revealed today.
Last year's winner of the Crowther Homes Swinton Hurdle at Haydock Park and Tote Cambridgeshire at Newmarket had been 14-1 co-second favourite for the first leg of the "spring double" with William Hill.
No Irish horse has won the Lincoln since 1984 when Saving Mercy scored for Dermot Weld, who took out Gold Chaser (20-1 with William Hill) but has left in top-weight Tarry Flynn.
Ante-post favourite Tayseer is on the brink of a confirmed place in the line-up after the withdrawal of 24 horses at the second forfeit stage.
The David Nicholls-trained six-year-old needs only two more horses above him in the handicap to come out at the five-day confirmation stage to make the safety limit of 24.
