COLIN Tizzard’s burgeoning training career received a significant boost after the addition of 15 horses from leading owners Alan and Ann Potts.

The trainer of popular chaser Cue Card, Native RiverTizz and last season’s star staying hurdler Thistlecrack, Tizzard is the beneficiary of Colm Murphy’s shock decision to retire, with the Potts’ moving all their horses based with the multiple Grade One-winning trainer from Ireland to Dorset.

Among the new arrivals are Sizing Granite, winner of the Maghull Novices’ Chase at Aintree last year, Bally Longford and Viconte Du Noyer.

Milborne Port handler Tizzard said: "We got the call on Friday and it’s lovely.

"Twelve of them are here now and there’s another three arriving next week.

"I think we’ve got 85 horses now, which is great.’’

Earlier this month it was announced the Potts had removed all the horses they had in training with Henry de Bromhead, trainer of the great Sizing Europe.

Several of the string moved to Murphy’s yard in County Wexford.
