"Judge Simon Ward imposed a 30-month sentence on Lister, of Palmer Close, Wednesfield, Wolverhampton, after the now 19-year-old admitted wounding.
Pearson, now 16, of Ettingshall Road, Wolverhampton, also admitted wounding and was given a one-year detention and training order for his part in what Judge Ward described as the "gratuitous degradation" of the victim.
Prosecutor John Hallissey told the court young children had witnessed the attack on March 7.
None of those convicted of wounding attended the match, instead gathering a pub, the court heard."
