Mark Stewart has been brought in to replace Ethan Hayter in today's madison.
Stewart was the travelling reserve for the men's endurance squad, meaning he is on standby to step in and compete if needed.
The track team has had four travelling reserves here in Paris - Stewart, Joe Truman (men's sprint), Meg Barker (women's endurance) and Lowri Thomas (women's sprint). They have all been in and around the velodrome all week.
Thomas has often had a camera in her hand, taking some really lovely behind-the-scenes photos that British Cycling have been sharing on their social media channels. Check them out, external.
