It's the Kryptonite which reduces NRL premiers St George Illawarra to the ranks of mere mortals - Monday night football.

While clubs around the league bemoan its existence because of the massive impact Monday night games have on their bottom line, the Dragons have found securing the two competition points can be just as hard as getting fans to turn up to games on a weeknight.

With a grand final triumph, back-to-back minor premierships, and another solid start to this year's campaign with four wins from five games, it's not hard to see why the Dragons have been labelled the NRL's yardstick since the arrival of super coach Wayne Bennett.

But 'Monday-itis' has dragged down the Dragons, who have just one win from four games since 2009 a statistic that would have every South Sydney fan salivating ahead of Monday night's clash at ANZ Stadium.

On games played every other day of the week since Bennett's arrival, the Dragons boast a stunning winning rate of 73 per cent - 40 wins from 55 games.

"I don't think our record's been particularly good on Monday nights, but we've just go to go out there do our job, perform our roles," Dragons hooker Nathan Fien said.

"We've had a couple of days off earlier this week so we've had a lighter week.

"It's business as usual for us, it doesn't matter what day we play - they've got to play on Monday night as well so there's really no excuses there."

The Dragons held the second of their school holidays clinics in Wollongong on Wednesday, with players taking part after completing a light weights session.

The squad will train again on Friday, with NSW Origin front rower Michael Weyman - who hasn't played since round two - to test out his groin as he attempts to prove his fitness ahead of the meeting with the Rabbitohs.

Weyman wasn't expected to return until the round seven Anzac Day clash with Sydney Roosters, but has been running freely for the past fortnight and would be a welcomeboost as the Dragons look to combat Rabbitohs big men Roy Asotasi, Dave Taylor and Sam Burgess.
