Covid-19 tests all negative for Wigan Warriors clash with Hull FC
Wigan and opponents Hull FC have no Covid-19 worries heading into Thursday's semi-final.
And St Helens and Catalans, who meet the following day, also reported no positive tests from their wave of testing on Monday.
The news will be a major relief for Super League bosses, who had even kept Warrington and Leeds - beaten in the play-offs opening round - on stand-by in case a team had to withdraw due to a high number of Covid-19 cases and couldn't play on a rescheduled date.
