ATP Withdrawal Deadlines: Why an Entry List Can Change Hours Before the Draw

An ATP entry list can change on the day a tournament draw is made because the list records accepted players at a particular stage; it is not a promise that every player will compete. The ATP has advance entry deadlines, a separate late-withdrawal threshold, and rules for replacing a player who pulls out. Those clocks overlap near tournament week, so an update shortly before the draw can be valid. If you want to know who has an opponent, check the current official draw—not an older entry list or a reposted bracket.

The key distinction is simple: an ATP entry list shows who was accepted, while the draw shows the matchups after the event’s draw process. Neither is a guarantee that no later withdrawal will occur.

Entry deadlines, late withdrawals, and draw time are different clocks

The 2026 ATP Official Rulebook sets advance entry and withdrawal dates by event type. For singles, the main-draw deadline is noon Eastern Time (ET) 28 days before the Monday of an ATP Tour tournament week. For an ATP Challenger Tour main draw, it is noon ET 21 days before that Monday. Qualifying lists have their own deadlines.

These advance dates shape the acceptance lists well before the event. They do not mean that the field is guaranteed to remain unchanged until the first match. A player may withdraw later, including close to the draw, and the tournament then applies the replacement procedure for that stage. The current ATP rulebook is linked on the ATP Official Rulebook page or open the 2026 ATP Official Rulebook, April 27 PDF; its competition chapter contains the entry, draw, and vacancy rules.

What does Friday at 10 a.m. ET mean?

Friday at 10 a.m. Eastern Time, USA, before tournament week is a key late-withdrawal threshold. A withdrawal after that point can be treated as late and may carry a fine or ranking consequence under the applicable rules. Exceptions exist, including specified medical circumstances. The threshold concerns a player’s obligations; it is not a universal lock on the public field. A player can still withdraw after it, and the event may still need to fill a vacancy.

There is a separate draw-time rule. For the singles main draw, the 2026 rulebook says the public draw is made no earlier than 10 a.m. ET on the Friday before tournament week. The standard latest time is 10 p.m. in the event’s local time two days before the first day of play, unless ATP gives prior permission; approved Sunday starts have a separate latest-time provision. Because draw timing is set for each event, a withdrawal and a replacement can be confirmed only hours before a particular draw is published.

ET changes between Eastern Standard Time and Eastern Daylight Time over the year. If you convert the Friday threshold to another time zone, use the offset in force on that exact date; “10 a.m. ET” is not always the same UTC time.

How is an open spot filled?

The replacement depends on whether qualifying has started and who remains eligible. Before qualifying begins, a main-draw vacancy after the withdrawal deadline is generally filled in ranking order from the original main-draw acceptance list by players who preserved their place under the rules. If no eligible player remains on that list, the rules provide a route through qualifying or alternate lists. That is why “the next name on the list” is not always enough to identify the replacement: a player’s list position and eligibility matter.

Once qualifying has started, the applicable vacancy procedure uses the eligible lucky loser and alternate list. A lucky loser is a player who lost in qualifying but can enter the main draw after a vacancy. An alternate is a player waiting to move into a draw without earning a qualifying win. The rules place qualifying losers ahead of remaining alternates, with the precise selection depending on when the withdrawal occurs and the stage qualifying has reached.

If qualifying is still underway, the replacement may be determined through the process for that stage. After qualifying is complete, eligible players who lost in the final qualifying round are considered under lucky-loser selection rules. So a player who appears as “Qualifier / Lucky Loser” in a draw is not necessarily a direct acceptance who was simply moved up. ATP’s explanation of the lucky-loser process describes how the timing of a main-draw withdrawal affects eligibility.

Where should fans recheck the draw?

1. Open the event’s official ATP draw page and select the correct competition, such as singles or qualifying.
2. Check whether the page is an entry list, a qualifying draw, or the main draw. These are different records.
3. Look for a replacement label such as “Alt,” “Q,” “LL,” or “Qualifier / Lucky Loser,” and compare the page’s latest update with any announcement from the tournament.
4. Recheck after qualifying ends and again before the match. A confirmed bracket and a match schedule are separate updates, so verify the order of play and match time too.

For ATP Tour events, use ATP Scores, Draws & Schedules. Challenger events have a separate ATP Challenger scores, draws, and schedules page. If a social post conflicts with the live official draw, compare timestamps and wait for the event or ATP page to reflect the change before treating a matchup as final.

What this guide covers

This explanation follows the April 2026 update to the 2026 ATP rules for ATP Tour and ATP Challenger Tour events. Grand Slam tournaments publish their own regulations and operational notices, so do not assume every ATP Tour vacancy procedure applies unchanged at a major. Rule details can also vary with tournament category and draw stage. The safest check is always the event’s latest official draw, followed by the schedule for the match itself.
