Walsh Faces Month On The Sidelines Jockey Ruby Walsh is set to be out of action for up to a month after X-rays showed he has aggravated the injury he received at Cheltenham nearly four weeks ago. Walsh was hurt when the Frances Crowley-trained Riverboatman fell at the second-last in the `Ashkalani´ at Coolamurry Stud Carey´s Cottage Cup Handicap at Gowran Park on Thursday. The in-form rider missed the first two weeks of January after a double spill at Prestbury Park on New Year´s Day. 'He has aggravated the injury he sustained at Cheltenham,' said his sister and agent Jennifer Walsh. 'He will be out of action for up to a month and during that time he will need physiotherapy consistently.' ? PA Sport
