The under-21s match against Everton was due to take place at Aggborough at 7pm this evening, but the decision has been made alongside the official mourning guidance.
Similarly, the the under-18s' planned meeting with Leeds United, scheduled for tomorrow at Thorp Arch Grange, will no longer take place.
On Sunday, the women’s first-team were set to face Northampton, but that fixture will also no longer take place as a mark of respect.
Further information and rearranged dates will be confirmed in due course.
