Richard Agar admits the threat of a Covid-19 outbreak in Challenge Cup week is a growing concern with Leeds’ clash with Castleford tonight in doubt after more positive cases.
Three Tigers players have contracted the virus and a further six have been stood down through test and trace, leaving them with only 14 fit men at present.
Three more will have fitness tests on Thursday morning before a decision is made on the Yorkshire derby, one of two matches Agar’s squad have to navigate before their Wembley showdown with Salford on October 17.
The Rhinos had to delay their Wednesday training session while some of their players were cleared on test on trace, after a third positive case at last Saturday’s opponents Wigan.
