Adrian Maguire has been all but ruled out of action for the rest of the jumps season. Medical consultations yesterday morning found he had refractured the collar-bone he broke at Cheltenham last month when falling at Ascot on Tuesday.

The jockey, hitherto on the crest of wave after wins on Baronet in the Scottish Grand National and Call It A Day in the Whitbread Gold Cup, is resigned to missing out, for the third season in-a-row, on reaching 100 winners. "I went to see Michael Foy this morning and I have refractured the collar-bone," Maguire said.

"It is not a complicated break but I am looking at being out for at least three weeks, if not longer.

"That virtually rules me out until the end of the season. I am on 93 winners and only needed seven more to reach 100 but realistically that is not possible now. But I will be back riding in the summer.

"It could have been worse. At least I was able to come back and salvage the last two big races of the season, so that wasn't too bad."

Maguire has been badly hit by injury since he rode 194 winners in the 1994/5 season and narrowly missed his first jockeys' championship.

His tallies in the last two campaigns were just 60 and 81 victories.

He suffered his latest injury when falling at the third-last flight on Better Offer in a novice hurdle at Ascot.

Seamus Mullins sent out his 17th winner of the season in the Wivelsfield Green Handicap Chase at Plumpton yesterday when Scobie Girl beat Early Drinker by 22 lengths.
