Reads here like Connell wanted him to give up booked rides in order to school 2 of his horses. At least Ed Chamberlain just mentioned it in passing that Connell sacked O'Sullivan. https://www.irishmirror.ie/sport/horse-racing/irish-cheltenham-winning-trainer-jockey-34196295
Yeah that's what I said I thought there were a few occasions where they clashed heads, not the first time Barry O'Connell has done it to a jockey either. But then I suppose if you're hired by someone to do a job and you don't do it then you're going to be fired. Problem is he doesn't have enough horses going to really have a retained rider of a certain calibre so I can understand both sides of the equation.
