Career Mode - Too few riders registered

Hi there,
In the Career Mode, I changed the team schedule to include the Ronda de Espana, but now I've reached the first day, I cannot begin the race because the manager is only selecting 8 riders to be part of the race whereas 9 riders are required. Is there some way to get around this issue?
Thanks
