The top Irish jump jockey sustained the injury in a fall from Let's Dance at Punchestown on November 18. He is hoping to have a smaller cast on his leg soon and aims to begin his physiotherapy in early February.
"The leg is good and seems fine. It's in plaster of Paris, so I can't do a whole pile with it, but it's not sore," Walsh told Racing UK. "It's been just over three weeks now so I'm counting down backwards with at least eight and a half to 10 and a half weeks to go before I'm back (riding). The plaster cast should come off after Christmas or New Year and is likely to be replaced by a smaller cast. I can then start the physio properly at the beginning of February, which means I should be at Prestbury Park come mid-March."
