Penrith centre Brad Tighe's possible one-match ban for a dangerous throw could open the door for dual international Timana Tahu to make an immediate return to the NRL this weekend.

Tighe was on Monday slapped with a grade one charge by the NRL match review committee after an ugly tackle in which Parramatta centre Paul Whatuira was dumped on his head in Friday night's local derby.

The charge attracted a base penalty of 125 points, but loading for a similar offence in the past two years bumped it up to 187-points, meaning Tighe will miss one game even if he accepts the early guilty plea.

Tahu will begin training with the Panthers this week after agreeing to a one-year deal with the club last Wednesday.

Panthers coach Matthew Elliott had indicated Tahu's most realistic avenue for a return would be off the bench as he regained fitness and acclimatised to the team's set-up. But Tighe's potential unavailability could see the former NSW Origin star - who walked out on the Eels over the off-season - rushed into the starting 13.

Two other players were also charged, with North Queensland's Gavin Cooper not in any danger of missing a game for a careless high tackle on Newcastle's Beau Henry.

Knights forward Zeb Taia can escape a one game ban if he pleads guilty to a grade two careless high tackle charge on Cooper.

All players have until midday on Tuesday to enter their pleas.
