Hull Kingston Rovers second-rower Con Mika has been given a one-match ban and a £300 fine for a dangerous high tackle on Hull FC centre Jordan Turner.
The incident happened during Hull KR's 32-18 defeat to city rivals Hull on Monday night.
Mika admitted the offence when he appeared in front of the Rugby Football League's disciplinary committee.
The player will already miss Sunday's game against Widnes with a torn hamstring he suffered in the Craven Park match.
