A marshal injured during last Friday's Senior T.T. race remains in a critical condition in Noble's hospital.
60 year old Hilary Musson sustained injuries in the incident at the 26th Milestone on the Mountain section, in which 34 year-old rider Mark Ramsbotham and two visiting spectators lost their lives.
According to messages left by her daughter Gail on the Manx Athletics website, Mrs Musson underwent surgery on Tuesday and it's hoped she may improve in the next few days.
Hundreds of people have logged onto the site to leave and read messages of support for Mrs Musson and her family.
Meanwhile, New Zealand rider Shaun Harris is said to be 'stable' in the Intensive Therapy Unit. He crashed at Union Mills in last Tuesday's Superstock race.
