Hull FC advanced to the quarter-finals of the Challenge Cup after a fiery 38-20 win over Championship outfit Featherstone.
Six yellow cards and one red were shown by referee Scott Mikalauskas in a bad-tempered contest.
Jake Connor ran the show, but it proved to be a costly night for the Black and Whites, who had Bureta Faraimo sent-off and suffered three serious injuries to Fetuli Talanoa, Carlos Tuimavave and Josh Bowden.
It was a flurry of tries in the opening 15 minutes that won Hull the game as they stormed into a 16-0 lead thanks to tries through Connor (2) and Sika Manu.
The game was even thereafter, the sides exchanged tries as Anthony Thackeray and Jamie Shaul scored, with Josh Griffin then extending the lead.
Luke Briscoe equalled Eric Harris’ 81-year record as he scored for a 17th successive game, meaning the first-half ended 30-10.
Briscoe bagged his brace after half-time, but Bureta Faraimo put the game to bed with two tries.
However, the game descended into chaos before that. It appeared to be instigated by a badly mistimed tackle by Misi Taulapapa on Jamie Shaul in the 47th minute, a tackle that went unpunished.
Thereafter, both teams lost their discipline. Briscoe was the first in the bin following a professional foul, and he was followed by Fev teammate John Davies for a high tackle.
Danny Washbrook was then given ten-minutes, with Gareth Hock scoring thereafter, before Connor and Brad Knowles were sent to cool down after an exchange.
Jamie Shaul became the sixth and final player to be sent to the bin for a professional foul, and after the hooter sounded, Bureta Faraimo was dismissed for a high tackle on Shaun Robinson.
