Frank Pritchard in his final regular season game for the Bulldogs.

Bulldogs forward Frank Pritchard will be free to play in Friday's sudden death semi-final with the Roosters at Allianz Stadium after successfully contesting his grade one dangerous contact charge at the NRL judiciary on Tuesday night.

Pritchard was cited for his challenge on Dragons five-eighth Gareth Widdop during the Bulldogs' 11-10 golden point victory on Saturday. 

Pritchard's challenge wasn't enough by itself to warrant a one-game suspension (with a base penalty of 75 points), but the Bulldogs forward has a prior non-similar offence in the past two years and 51 carryover points.

Cronulla hooker Michael Ennis narrowly escaped suspension with an early guilty plea for his careless high tackle on Rabbitohs forward Chris McQueen. Ennis will be available for Saturday night's sudden death clash with the Cowboys in Townsville.

South Sydney's Luke Keary will be suspended for one match for a grade one dangerous contact on Cronulla forward Paul Gallen, while Greg Inglis was hit with a grade one careless high tackle, but won't miss any matches.
