A CIVIL engineer denied two counts of violent assault when he appeared before Lewes Crown Court.
Daniel Lawson, 31, of Salisbury Road, St Leonards was arrested in March following the attack on George Gardiner.
Mr Gardiner was found lying on the ground at 6.30am on March 10 and was placed in a medically induced coma in hospital.
Lawson appeared via video link from HMP Lewes for the hearing on May 31.
He spoke only to confirm his name and to enter two not guilty pleas to the charges.
He is charged with one count of causing GBH with intent on March 10 against Mr Gardiner.
Lawson is also charged with assault causing ABH on March 9 against Stuart Stevens.
Prosecuting Dale Sullivan told the court he had been informed a bail application would be made next week.
He told Judge Richard Brown the trial was expected to last six or seven days and that the custody time limit is due to run out on September 30.
Frank McGrath, defending, said he would submit his defence statement by June 19. No trial fixture was made during the hearing.
