Big news.
Joseph O'Brien is one of the best loved flat jockeys around, but it's been no secret that the Kilkenny man has struggled with his weight since taking over as one of the main jockeys for his father Aidan.
The 22-year-old has won a number of Classics during his carrer, but has now decided that his life as a jockey is no-more when the season comes to an end shortly.
The jockey has decided to quit life on the horses and instead will now focus on training alongside his father for JP McManus.

According to
The Mirror O'Brien is set to train mostly jumpers for the Limerick man and will work out of the same yard as his father grew up in in south Kilkenny.
O'Brien has also done some jump racing but it's believed that the constant battle with weight has forced his decision to quit the saddle for the parade ring.
