Representative hopefuls Michael Ennis, Paul Gallen and Luke O'Donnell are all facing time on the sidelines after being charged by the NRL match review committee.

Ennis and Gallen are both facing one match bans while O'Donnell could be outed for two games after being charged with contrary conduct for throwing punches in North Queensland's win over Manly on Saturday night.

In-form Bulldogs No.9 Ennis was charged with placing unnecessary pressure arm and shoulder - in a manoeuvre commonly known as the `chicken wing' - with his 38 carry-over points proving particularly costly.

An early guilty plea or a guilty finding would rule Ennis out of Sunday's much-anticipated battle with NSW hooking rival Robbie Farah.

Gallen is eyeing his second suspension of the season after being charged over his high tackle on South Sydney utility Craig Wing.

The Cronulla skipper will miss one week with an early plea or a guilty finding.

Parramatta workhorse Nathan Hindmarsh will miss one game if he pleads guilty to a dangerous contact charge for his knees to the head of Brisbane skipper Darren Lockyer.

Hindmarsh could be outed for two games if he fights the charge and losses at the NRL judiciary on Wednesday night.

Canberra backrower Tom Leahroyd-Lahrs is facing one week after being charged with striking.

St George Illawarra youngster Matt Prior and Newcastle five-eighth Ben Rogers can both escape suspension with early pleas after being charged with grapple tackles.
