What Is Lineup Lock in DFS?

Last updated October 4, 2026 by Ship It Nation

Lineup lock is the deadline after which you cannot change your selected players. Without late swap, your entire lineup locks together; with late swap, which allows edits after the contest begins, players lock at their games' listed deadlines.

Why It Matters

Sunday kickoff windows create separate news deadlines in contests with late swap. Check official inactive lists for each window, and preserve eligible replacements for questionable afternoon players before your early-game choices lock. A replacement being active is not enough if his own game has already locked.

Example

Say your NFL contest allows late swap and includes both the 1 p.m. and 4:25 p.m. ET games. Your afternoon running back is declared inactive after the early games lock. You can replace him with an eligible, unlocked afternoon player who fits your remaining salary, but you cannot use a backup whose game locked at 1 p.m.

Pro tip

After saving an edit, reopen your entered lineups and confirm the change reached every intended entry. Check the site's displayed lock times and time zone instead of relying on the television schedule.

Hear Us Break It Down

Hand-picked moments from our free live streams where our hosts break down this term.

Why a delayed game can leave you choosing without lineups You may have to choose hitters before the batting order is available when the first game of a doubleheader runs late. The key uncertainty is whether the DFS lock time changes, not simply whether first pitch moves back. “If they don't change the lock time, we probably won't have lineups before this game is supposedly set to lock on DK because of the two-hour delay in the first game.” MLB · Friday, Sep 4 8:45 ▶ What missing the lineup deadline can cost you You see the consequence of not getting a lineup submitted before lock: the show points to entries sitting on zero. The discussion raises possible customer relief, but gives you no confirmed refund or resolution. NFL · Sunday, Sep 13 18:16 ▶

Common Questions

Does my whole DFS lineup lock when the first game starts?

Only if the contest does not offer late swap. In a late-swap contest, each game's listed deadline locks its players while later-game players remain editable. Check the specific contest rules because availability depends on the sport and format, not simply whether you use DraftKings or FanDuel.

What happens if my player is ruled out after lineup lock?

An inactive player who never participates generally scores zero, and you cannot manually replace him once his roster spot is locked. A later-game player may still be editable in a late-swap contest. Canceled or postponed events can have separate scoring, swap or refund rules.

Does a delayed game give me more time to edit my lineup?

Not automatically. A delayed start does not guarantee that the site's listed lock time changes. Check the contest's displayed status and applicable rules before waiting for news. Some postponement rules permit additional swaps, but those exceptions differ by site and contest.
