The Knights have the Cowboys this Sunday, and a loss may prove to be the end of their season.
"It's a real battle for a place between three or four teams all trying, like us, to gain momentum and string a couple of wins together,"
"In the case of Timana and Steve Simpson it's now like having one hand behind our backs. But it's just a matter of trying to be as healthy as we can be from now until the end." said Knights coach Michael Hagan.
This news comes only a few days after Knights second-rower Steve Simpson was ruled out for eight weeks.
