Warrington Wolves saw their second-highest attendance of the season against St Helens, while the Hull derby was confirmed as a sell-out during Super League Round 18.
Although no official figure was shared, Hull KR confirmed that Sunday’s televised fixture at Craven Park was at full capacity ahead of kick-off.
Tony Smith’s Black & Whites spoiled the party with a 16-6 victory in a derby that probably won’t live long in the memory.
Full-back Jack Walker opened the scoring for the hosts, before Adam Swift crossed twice, with team-mate and forward Ligi Sao crossing in between.
Friday night’s televised thriller saw a crowd of 12,385 inside the Halliwell Jones Stadium, with the travelling supporters packing out the away end behind the sticks.
It was a close encounter between Warrington and St Helens, with the visitors claiming a 24-20 victory to climb to third on the Super League table.
The attendance saw Warrington claim their second highest of the season so far behind the Round Nine clash against Wigan with 15,026.
