Reddin worked for England's Rugby Football Union as a fitness expert between 1997 and 2006, with the pinnacle being the World Cup success in Australia.

Reddin was also part of Woodward's backroom team on the British and Irish Lions tour of New Zealand in 2005.

After his spell working with Team GB, Reddin joined the FA in 2014 as head of performance services under then director of elite development Dan Ashworth.

Reddin's role initially focused on England's development teams but he was appointed head of team strategy and performance in 2016.

That role included responsibilities for performance medicine, analysis, physical performance, nutrition and people development.

Reddin worked with Gareth Southgate's senior England side, including at the 2018 World Cup when they reached the semi-final.

FA chief executive Martin Glenn said Reddin had played a "key role across all 28 of our England teams" when he left the organisation in 2019.

Reddin was subject to an FA investigation after a bullying allegation was made against him in 2017.

After a thorough process, the FA said it was "entirely satisfied the matters were appropriately investigated and concluded".
