Castleford's next two fixtures have been cancelled as the coronavirus pandemic continues to wreak havoc with the Betfred Super League.

The Tigers' game against Huddersfield last Friday was cancelled after 13 players tested positive for Covid-19 and their scheduled fixtures against Leeds on Friday and Salford next Monday have also gone after four more players caught the virus.

After the latest positive results, the Rugby Football League's 'Multiple Cases Group' has extended the shutdown of the club.

No decision has yet been made on Castleford's last scheduled fixture of the regular season against Wakefield, with two further rounds of testing to be carried out this week.

The latest development, allied to a second national lockdown coming into effect on Thursday, will be high on the agenda of a crucial Super League board meeting that was already due to take place on Monday.

Calls to bring an early end to the regular season and focus on the play-off series, possibly with more teams, were due to be discussed and are now likely to gain more support.
