Question 1

What are live in-game substitutions in fantasy football?

Accepted Answer

Live in-game substitutions let you swap a player out of your lineup during an in-progress NFL game — for example when a starter gets injured or underperforms. Any points the outgoing player already earned are frozen and kept, and the incoming player starts accumulating points from the moment of the swap.

Question 2

How does scoring work when I make a substitution?

Accepted Answer

A lineup slot total equals the Frozen Points (everything the players you subbed out already banked) plus the New Player’s Points (everything the current player earns after entering the slot). You never lose the points already scored — you only gain the new player’s production going forward.

Question 3

Is FantasyFootballSubs free to use?

Accepted Answer

Yes. FantasyFootballSubs is free to play. Create an account, build your roster, and start making real-time substitutions during live NFL games.

Question 4

Does the platform use real NFL data?

Accepted Answer

Yes. Live scores, player rosters, fantasy points, injury status, and standings are powered by real NFL data, so your decisions are based on real production and matchups.
