A total of nine Hull players and three staff members have now tested positive for coronavirus, Super League has confirmed.
Earlier this week, it was revealed that six players and two off-field staff had tested positive following the game against Salford on Sunday, which forced both clubs in to isolation and caused their games this weekend to be postponed.
Seven of the players who have tested positive featured against Salford, who have had no positive tests in two rounds of testing this week. They plan a further two rounds of testing in the coming days.
A spokesperson said: “Hull FC continue to work closely with the Rugby Football League and Public Health England. Both the club and Rugby League Cares are providing welfare support to the players and staff affected by Covid-19.”
The news from Hull has forced the postponement of their scheduled Challenge Cup game against Castleford next week – Salford aren’t due to be in action until August 29.
The remainder of Hull’s players, coaches and backroom staff have returned negative results for a second time.
