The race had to be re-started after, on lap three of the original six-lap Senior, Wilson Craig Honda rider Guy Martin crashed heavily at Ballagarey. His bike burst into flames, bringing out the red flag so fire engines could attend.
Despite initial fears for Martin, the popular racer was reported to be conscious and talking at the scene and was airlifted to hospital with chest injuries and minor fractures to his upper spine.
It has now been confirmed he is due to leave Noble's Hospital in the Isle of Man today or tomorrow.
Karsten Schmidt, who crashed during the first Supersport race, has been moved to a hospital in his native Germany. Sidecar passenger Joseph Shardlow remains in hospital, where his condition is described as comfortable and improving, while Pete Alton requires further treatment on a leg injury.
