Lance Hohaia has accepted a one-match ban for his forearm strike which sparked the punches from Ben Flower during a brutal opening to Saturday's Super League grand final between St Helens and Wigan.
The 31-year-old New Zealand playmaker, who caught Flower off the ball, was knocked to the ground by the Wigan prop's first punch and then lay motionless as Flower landed a second on his face.
Flower will face a Rugby Football League disciplinary tribunal today charged with a grade F offence, which carries a minimum eight-match ban.
Hohaia was charged with a grade B offence of striking which normally carries a suspension of one or two matches.
Because of his previous record, the St Helens half-back was entitled to submit an early guilty plea to receive the smallest sanction and avoid a hearing.
