Trainer Laura Mongan has been left searching for a replacement rider for Alsadaa in tomorrow’s Anglo Irish Bank Tolworth Hurdle after regular partner Colin Bolger suffered an injury at Lingfield.

Laura Mongan will not risk Alsadaa in Saturday’s Anglo Irish Bank Tolworth Hurdle at Sandown if the ground is testing.

Jack The Giant slayed the bookmakers as the result of a monumental gamble in The Ladbroke at Ascot.

Laura Mongan is optimistic Alsadaa can do her Epsom stable proud in the Ladbroke Handicap Hurdle at Ascot on Saturday.

Osana, who could yet contest this Saturday’s Boylesports.com International Hurdle, is the top-weight and ante-post favourite for the Ladbroke at Ascot seven days later.
