Betts was a winger whose Football League career lasted from 1936 – 1939. His promising playing career was cut short due to injury in a match versus Coventry City. Betts was paid compensation by the league's insurers in 1941 having been told by doctors he would never play again, following major surgery to his injured knee. After convalescing, Betts regained fitness through a determined personal effort and expensive remedial physiotherapy. After an extraordinary recovery, regardless of medical opinion, Betts was asked to play again for Forest, having been spotted by an official excelling in the field at Cricket. Betts played in reserve team matches and one first team match, against Chesterfield F.C. in the 1944 war time Football League-North First Championship, over 5 years after his last first class match for Forest. Nevertheless, hopes of a long term comeback for Betts were dashed as league rules, which prevented a player from returning after receiving compensation, were imposed. Irrespective of his offer to repay his £350 compensation payment, the league's rules were upheld and Betts's professional career came to a premature end.
