One of the most popular horses on the Flat, Pyledriver, has been retired from racing.

Co-trainer William Muir announced on Tuesday that the recurrence of a ligament injury has led connections to call time on his outstanding career.

It was the latest of a number of training setbacks to have dogged the career of the six-year-old.

Despite those interruptions he managed to deliver Muir and partner Chris Grassick their first G1 success when he won the Coronation Cup in 2021.

The following year he added the King George VI and Queen Elizabeth Stakes at Ascot. He won twice at Royal Ascot, capturing the Hardwicke Stakes and had total earnings of £2 million.
