Dowling broke his shoulder and collarbone during a fall in the Chancellor Of The FormChecker Handicap Hurdle at Fontwell
Irish conditional jockey Tommy Dowling is on the road to recovery after his operation, but trainer Charlie Mann has refused to be drawn on putting a timescale on his recovery.
It was initially thought that Dowling would be ruled out for six months after the fall, after he fell from Mann-trained My Anchor at the first flight in a handicap hurdle at Fontwell last Friday.
"He had two steel rods put in his back on Sunday at a hospital in Brighton" he told Sporting Life.
"I don't know how long he's going to be out as he's had a bad fall and broken lots of bones."
Dowling was stretchered off the course and taken to Royal Sussex County Hospital in Brighton for treatment following the fall.
