Keighley player-coach Paul March has been charged with the Grade C offence of questioning the integrity of a match official.
March, 34, was sin-binned for his part in a melee shortly before half-time in the Cougars’ 30-12 defeat at Doncaster. Then in the 43rd minute he commited the offence involving the match official.
March does not have the option of submitting an Early Guilty Plea and he will appear before an RFL Disciplinary Tribunal on Tuesday evening.
Keighley started the season with a win over Whitehaven, and after the defeat to Doncaster they now travel to Rochdale on Sunday looking for a return to form.
