O'Regan and Johnson split The partnership between Denis O'Regan and Howard Johnson has come to an end, with the trainer revealing on Sunday that O'Regan's retainer with his main patron, Graham Wylie, will not be renewed. O'Regan was given a three-year contract by Wylie in 2007, but the owner does not intend to retain a jockey any longer. Johnson informed O'Regan of the decision on Saturday evening, and said "there is no bad blood between me and Denis, and I wish him the best of luck, but Mr Wylie is not going to retain a jockey any more. "I will use the best available jockey at Hexham and Perth this week, and Brian Hughes, Wilson Renwick and Ryan Mania will be riding for me." O'Regan, who replaced Paddy Brennan as Johnson and Wylie's number one, has won the Ladbrokes World Hurdle on Inglis Drever and Irish Independent Arkle Trophy on Tidal Bay for them, and last weekend finished runner-up on the Dessie Hughes-trained Black Apalachi in the John Smith's Grand National.
