If there's a jockey change for your selected runner, here's what you need to know:

1. Selection Remains Valid:
   • Your selection stays in place despite the jockey change
     
     
2. Options to Change:
   • Before the Showdown goes live: You can change your selection
   • After the Showdown is live: Changes only possible with a Re-Buy (if available)
     
     
3. Re-Buy Option:
   • If offered, a Re-Buy allows changes to later legs
   • Check Re-Buy availability and rules for your specific Showdown
     
     
4. Timing Considerations:
   • Be aware of when the Showdown "goes live"
   • Make any desired changes before this deadline
     
     
5. Strategy Impact:
   • Consider how a jockey change might affect your runner's chances
   • Decide if you want to stick with your selection or make a change
     
     

Remember, while a jockey change doesn't invalidate your selection, you have options to adjust if you act within the specified timeframes or use a Re-Buy when available.
