Canberra centre Joseph Leilua has been charged with dangerous contact on Newcastle's Tim Glasby, although can avoid suspension with an early plea.
Leilua was charged after an incident in the 68th minute, after he reacted to a tackle from Glasby.
The Raiders centre lashed out with an elbow and connected with Glasby's head, sending him to the turf.
If he challenges the charge and is found guilty, he'll miss one match.
