Harry Smith is free to feature in Wigan's World Club Challenge clash with Penrith after escaping a ban for his tip-tackle on Castleford's Luke Hooley in Friday night's Super League opener.
Wigan are seeking to make it back-to-back wins for English clubs after St Helen's beat Penrith Down Under last year.
Smith, 24, was sent to the sin bin following the incident but received a Grade B charge because the RFL's match review panel found that "the unnatural actions of the tackled player significantly contributed to the outcome of the tackle".
Grade B charges generally incur a one-match ban, but previous conduct can provide a mitigating circumstance and the halfback, a pivotal figure in Wigan's hopes of emulating St Helens on Saturday, got away with a £250 ($A480) fine.
