Trifolium undergoes small wind operation Charles Byrnes has said he was stunned by the disappointing showing from Trifolium at Punchestown last week. The Supreme Novice Hurdle third, was sent off the 8/15 favourite to score on his seasonal debut in the Grade 3 Ryan's Cleaning Events Specialists Hurdle at Punchestown last Thursday but he trailed home thirty-two lengths second to Miley Shah. Byrnes said after the success of Moscow Chief in the bumper at Tipperary this afternoon: "We were stunned by his run and Davy (Russell) said that he was beaten after the first hurdle. “He has undergone a wind operation since but won’t be out for too long as it was only a small operation.”
