Canterbury's Luke Thompson is facing a premature end to his NRL season unless he can successfully beat a crusher tackle charge at the judiciary.
Thompson, making his return from a three-game ban, was placed on report late in the Bulldogs' loss to Newcastle at Cbus Super Stadium on Saturday.
The judiciary has charged the England international with a grade one offence, meaning even if he takes an early guilty plea his season would be over with a two-game ban.
Given his poor history, which includes three non-similar offences in the past two years, Thompson would be out for three matches if he challenges the ban and loses.
Back-rower Corey Waddell is also facing a one-match ban after he was charged with contrary conduct against the Knights.
Waddell, who had only just been placed on report for a high tackle minutes earlier, was cited for a second time in the game after being caught on camera pulling the headgear of Kalyn Ponga.
Waddell will miss next weekend's clash with Manly whether he enters an early plea or not.
Bulldogs coach Trent Barrett admitted the offence with Ponga was "silly" by Waddell and not helping his struggling team's cause.
"We've got to get them out of our game because it certainly doesn't help," Barrett said.
"It compounds on the errors that we're making as well so it's something we need to address it and individuals have to address as well."
Newcastle prop David Klemmer has been charged with a grade one contrary conduct offence on Thompson and is also facing a week out regardless of his plea.
Meanwhile, South Sydney's Keaon Koloamatangi has accepted the early plea on a grade one crusher tackle on Penrith winger Brent Naden and will miss the Rabbitohs' final two home-and-away matches before returning for the first week of finals.
