Bradford Bulls have promoted three players from their academy to their Super League squad for 2013.

Centre Sam Wood, 18, has signed a two-year contract while full-back Curtis Naughton and back-rower Oliver Roberts, both 17, have been handed three-year deals.

“It’s fair reward for the progress they have made since joining us last year and they are now going to find out what being a full-time professional is all about,” said Bulls head coach Francis Cummins
