Doncaster Knights completed two deadline day signings with the arrival of Oli Bryant and Zach Kibirige on dual registrations.
Leicester Tigers fly half Bryant has featured for the Knights sporadically over the past three seasons.
The 21-year-old has played a significant role in the Tigers’ Anglo Welsh Cup squad this season and made his first Tigers start against Saracens at Allianz Park last month.
Newcastle Falcons winger Kibirige scored against Doncaster in pre-season.
The 22-year old has represented England at Under 17, 18 and 20 level. He has made 20 first team appearances for Falcons, touching down 11 times.
“They are two players with Premiership experience and will add strength to our squad for the vital five Championship matches ahead and hopefully another play-off campaign,” said director of rugby Clive Griffiths.
“Oli is well known to Knights fans of course and was on the opposite side of the fence recently when he appeared in Rotherham colours.
“Zach has an outstanding rugby pedigree and anyone who witnessed his individual try against Bath recently will know that we have another top class finisher in our ranks.”
Centre Nick Carpenter and prop Saba Meunargia joined Knights last week.
