DUO betting and substitute protection
DUO is an operator market label. Where the rules include a player and their replacement, both may contribute to the selected bet. The name alone does not establish which statistics count or which competitions qualify.
How substitution protection works
Read the full label before staking. Compare the statistic, eligible competitions, starting-player requirement, substitution timing and settlement method. Protection does not guarantee a winning bet.

Market coverage by competitionFrequently asked questions
Does the substitute count?
Only when the selected market explicitly includes the replacement. Check whether the original player must start, which substitute qualifies, and whether a later replacement is included.
Are all substitution-protected bets settled in the same way?
No. A bet may transfer, combine statistics, or qualify for a separate payout. Ordinary player markets without the relevant label are not automatically protected.
Which bookmakers offer this market?
No matching country-specific market record is available in this directory. This does not establish that every bookmaker lacks the market; check the operator’s current terms.
