Daniel Sullivan, 47, is facing 14 years in prison for attacking Noel Gallagher onstage in Toronto last year.

Sullivan was initially charged with assault which carries a maximum of 5 years in prison but has been upgraded to aggravated assault which is 14 years.

The assault left Gallagher with broken ribs when Sullivan came onstage and pushed him while in performing. Oasis cancelled some shows to allow Gallagher to recover.

Sullivan is due in court on March 6 for the pre-trial hearing.
