Rabbitohs coach Michael Maguire has suggested Sam Burgess suffered a potentially dangerous neck injury due to a habit he picked up from rugby union.
South Sydney are expecting Burgess to return from his neck injury against Manly next week, but remain unclear as to what mental scars the incident has left on the English superstar.
Burgess is expected back at Rabbitohs training as early as Thursday after being released from hospital on Tuesday.
Burgess was zero chance of lining up in the Good Friday blockbuster against 2014 grand final opponents Canterbury according to Maguire, with Thursday week's clash against the Sea Eagles the target after he was cleared of any damage to his neck.
Maguire said the 27-year-old would have to work on his technique, suggesting his tendency to duck his head as he attacked the line was a bad habit he adopted during his stint in rugby union last year.
