Bradford, Brown, Planchant and Boyde handed new contracts
Doncaster have continued their rebuilding for the 2012/13 RFU Championship season by agreeing new deals with David Bradford, Andy Brown, Chris Planchant and Andy Boyde.
Bradford has scored five tries in 12 starts - including three in his first three games - since the 24-year-old flanker joined from Ulster in the summer.
Former Leicester academy graduate Brown has made 19 appearances in his debut season at Castle Park, with the prop having made the move from Cambridge.
Popular No.8 Planchant is currently in his second spell at the Knights, with a knee injury ending his first stint at the club in 2010.
However Planchant rediscovered his form and Pontefract and returned to Castle Park - with the strong, ball-carrier now earning another 12-month deal.
Former England Under-19s captain Boyde joins fellow back-rowers Bradford and Planchant in committing to the club.
The blindside flanker has racked up 66 appearances since joining from Leeds in 2009.
