Daniel Gregory began playing rugby union at the age of 12 before switching to rugby league when he was 13 and joining Staines Titans. In 2008 he was spotted by the London Broncos Assistant Strength and Conditioning Coach Andy Flint who invited him to a trial. Gregory was successful and has been at the Broncos ever since. 

Gregory's favourite film is the longest yard and he enjoys spending time with friends and going to the gym.
