Wairarapa Bush flanker Sam Marshall-Wilson has been banned from all rugby for five weeks -- a sentence including the remainder of this year's Heartland Championship and the start of next year's club season.
Marshall-Wilson was cited under law 10.4 (a) by NZRFU citing commissioner Mike O'Leary for striking Wanganui first five-eighth Dane Whale in the 43rd minute of their match at Cooks Gardens last Saturday. Wanganui won the match 38-24.
The Eketahuna utility forward admitted throwing the punch which was described as "felling" Whale after an altercation in a ruck.
Whale was sent to hospital where it was found he had a broken jaw.
The injury required surgery.
