The NRL is investigating four Gold Coast Titans players who were allegedly playing the pokies in a Sydney pub without masks.
Among the group was New Zealand international and club co-captain Kevin Proctor, Gold Coast coach Justin Holbrook confirmed.
He said the hard-running second-rower and three of his teammates were cooperating with the NRL probe as they prepare for Saturday's clash with the Canberra Raiders at Jubilee Oval in Kogarah.
Two other big names in rugby league are facing possible sanctions after being photographed at the Tim Tzsyu boxing match in Newcastle without a mask on Wednesday night.
