They are officially the most promoted team in English rugby union history.
During 13 years in the 90's and naughties the Doncaster Knights moved up seven divisions.
But despite their league success, cup glory has so far eluded them.
But that could be put right tomorrow when the Knights take on Worcester in the final of the British and Irish Cup.
Chris Dawkes reports:
Doncaster Knights have signed Ben Hooper from Leeds Carnegie on loan until the end of the season. The front-rower will join up with Clive Griffiths' side for the remainder of the Championship season.
Doncaster Knights have signed Newport Gwent Dragons hooker Rhys Buckley for the 2012/13 season.
22 year-old Buckley has graduated through the professional youth set-up in South Wales.
He spent two years in the Principality Premiership for Pontypool before being picked up by his region.
