"The health and welfare of our players, staff, fans and partners is always our primary concern."
St Helens coach Kristian Woolf called on Super League and the Rugby
Football League to make a clear decision on whether the competition will be shut down following his side's defeat to Castleford.

Castleford coach Daryl Powell added: "It's pretty tough at the moment. There's an eerie feeling around everywhere. It will be the same for everybody, it will be difficult.
"We have to try and found a way of managing it best that we can. Nobody knows where it's going to take us over the next weeks and months."
