In-form Hull KR will be good test for St Helens - Mike Rush

St Helens interim coach Mike Rush tells BBC Radio Merseyside that Friday's fixture against Hull KR will be between two of the form teams in Super League.

Although KR are coming off the back of a Catalan Dragons defeat, it was their first loss in five matches.

Saints meanwhile lie fourth in the SL table, having only lost once in their last eight Super League games.
