North Queensland will employ minders for players after forward Scott Bolton admitted to drunkenly touching a woman's upper thigh in a Sydney court this week.

Cowboys coach Paul Green said they would introduce extra safety measures for players when they go out socially in future after Bolton pleaded guilty to common assault in Waverley Local Court on Monday.

Green said the Cowboys were also in discussions with the NRL over a possible penalty for the married prop regarding the charge.

Bolton avoided conviction and was put on a 12-month good behaviour release order after a charge of indecent assault was withdrawn over the incident at Bondi Beach Public Bar in May last year.
