Bradford coach Mick Potter admitted his side's record Super League defeat put a huge dampener on the club's takeover celebrations.
The Bulls conceded 13 tries in a 70-6 hammering by Hull, which eclipsed their 66-4 loss to St Helens in 2005, to suffer a body blow to their play-off hopes. The defeat came just 24 hours after local restaurant owner Omar Khan announced he had bought the club from administrator Brendan Guilfoyle.
"It was good news for everyone here but it's a pity we couldn't back that up with a good result," said Potter, who is now hoping to be officially reinstated ahead of next Saturday's final game of the regular season after working unpaid for the last two months.
The Bulls, who went into the game on the back of a three-match winning run, raced into a 6-0 lead with an early try from winger Jason Crookes, who is expected to join Hull next season, but controversially lost stand-off Ben Jeffries to the sin-bin and conceded two tries while down to 12 men.
"We deserve what we got, although I thought it was big decision early," Potter added. "Ten minutes in the bin for Ben Jeffries was a ridiculous call. The rot started from there. It's not the reason we lost but we were certainly on the back foot from then.
"We dug ourselves into a big hole and couldn't get out of it, while they got better as the game went on.
"There were a lot of things uncharacteristic of our players but it wasn't good enough. We know the players can do better and that's the disappointing thing.
"Confidence is something you can lose very quickly. We were building that but it has taken a massive hit tonight."
Hull winger Tom Briscoe scored a hat-trick of tries and Jamie Foster scored 26 points as Peter Gentle's men bounced back in impressive fashion from their humiliating loss to bottom club Widnes to cement sixth place in the table and breathe new life into their play-off campaign.
"We owed a lot of people a performance like that," said Gentle. "We came here with a semi-final mentality and we knew it would be intense but I never dreamt there would be a scoreline like that."
