“It’s a great honour to be called up,” said Myler. “I feel lucky to be going out there and playing Super League every week but this really is a big deal for me.
“The club have been great and I really have to thank them for giving me the opportunity to play in Super League. I now have another great opportunity ahead of me and intend to go out and make the most of it.”
