How bad is Robinson's injury from the Wigan game, does anyone know?

I spoke to Hecks and David Howell about Robinsons injury and they both seemed to think that it was just a knock on the knee and nothing to get too worried about ....Hope Dr's Heckenberg and Howells are right in their diagnosis..

I hope so too. Cant have him and Cougar both missing. He'll probably have 'water on the knee but I guess they will drain that off for Salford game
