Ryles, who has overcome foot and hamstring injuries this season to play for the Dragons, will now be sidelined again with what he hopes is a minor AC joint injury.
“Until the doctor (Dragons team doctor Martin Raftery) looks at it tomorrow we won't know for sure how long I'll be out, but the post-match assessment was that I am a good chance to be fit for the next Origin game (June 25),” Ryles said.
“It happened in my very first run. I was tackled and landed on the point of my shoulder. Before then I had not had any problems with my shoulder.�
“They will have a medical review late tomorrow afternoon to give them every opportunity to play,” said Brown.
Brown will not name a replacement for Ryles until tomorrow night.
Ryles joins captain Trent Barrett (ankle), centre Mark Gasnier (knee) and winger Amos Roberts (shoulder) on the Dragons injury bench.
