A rugby-mad student battled through the pain to score top grades in his A-levels despite being unaware he had broken his wrist.
Sam Adamson, 18, struggled through lengthy written papers after picking up an injury in a tournament.
Barnard Castle School's outgoing head boy, and vice captain of the first XV, will require surgery to fix the break in his scaphoid bone.
Nevertheless, the teenager, from Hunwick, County Durham, was still able to score A*s in chemistry, maths, further maths and a rare Distinction Level 1 in physics.
Sam, who plays second or back row, will read natural sciences at Durham University, where he plans to continue playing rugby.
