Leeds full-back Zak Hardaker is to be investigated once more for using homophobic language.

The Rugby Football League have confirmed they have launched a probe into allegations that the 22-year-old used inappropriate language during the Rhinos team’s 13-12 defeat by St Helens.

Hardaker, who was banned for five matches in June after being found guilty of homophobic abuse of a referee, is thought to have directed his comments towards Saints second rower Mark Flanagan.

“We are investigating an alleged comment made by Hardaker during the Super League match against St Helens,” said an RFL spokesman.

If Hardaker is charged and found guilty, he could face a suspension of up to eight matches, which would end his season with Leeds and cast a doubt over playing for England in the Four Nations.
