Say it isn't so!
RCG took a hit up in the Penrith Panthers' clash with the Sydney Roosters and came off second best with Jared Waerea-Hargreaves in a battle of the hyphenated names.
"I went up and saw Reagan, he's not in a good way," Fittler said on Channel Nine's coverage of the match.
"It was a shoulder from Jared Waerea-Hargreaves, and the doctor said he can clench his jaw which is a good sign, but there's a lot of pain underneath it.
"When I was speaking to him, he was in a lot of pain and it's a bit swollen already, he'll have scans tomorrow."

Channel Nine reported that the incident left RCG with a broken jaw.
The Panthers big man copped a shoulder or head from Waerea-Hargreaves, and looked in horrible shape as he left the Allianz Stadium.
Initial reports are a broken jaw for Regan Campbell-Gillard and the video doesn’t look good. If confirmed most fall in the 4-6 week recovery range, if severe break can be up to 10 weeks #NRLRoostersPanthers pic.twitter.com/4iEWMJ7yrj

If the initial diagnosis is confirmed, you can well and truly rule out Campbell-Gillard for the rest of the Origin series.

RCG wasn't the only Origin star to go off injured, with Maroons prop Dylan Napa leaving the field with a rolled ankle.
Worry for high ankle (syndesmosis) sprain for Dylan Napa, left foot rolled out as defender landed on top. Would have to be low grade injury to be fit for Origin #NRLRoostersPanthers pic.twitter.com/x99CbcKZnO
