The boy was treated in hospital for his injuries following the fight between rival groups of `moshers' and 'chavs' at Wilmslow High.
It is understood the fight was filmed on a mobile phone and posted on the internet. Parents said the school has suspended nine pupils following an investigation into the fight.
The 2,331-pupil comprehensive breaks up for the summer holidays tomorrow and staff have assured parents that the issue will be addressed in the next school year.
Police are not investigating.
