Fastest 40-Yard Dash at the NFL Combine

The fastest 40-yard dash in NFL Combine history belongs to wide receiver Xavier Worthy, who ran 4.21 seconds in 2024. His run edged the previous record of 4.22 seconds, set by John Ross in 2017, by a single hundredth of a second.

The 40-yard dash is the Combine’s marquee event, the number that can lift a prospect’s draft stock overnight. Since the NFL adopted electronic timing in 1999, only a handful of players have broken 4.25, and the very fastest are almost all wide receivers and defensive backs. Here is the full leaderboard of the fastest 40-yard dashes in Combine history, the context behind the times, and why speed alone is never the whole picture. All figures are as of the 2025 season.

The record holder: Xavier Worthy at 4.21 seconds

Xavier Worthy arrived at the 2024 Combine as a slight but explosive Texas receiver, and his 4.21-second dash instantly made history. He was later drafted in the first round by the Kansas City Chiefs, where his speed became a weapon in one of the league’s best offenses. Breaking a record that had stood since 2017, even by a hundredth of a second, cemented Worthy as the fastest athlete the Combine has ever timed.

The full leaderboard of the fastest 40-yard dashes

The table below ranks the fastest electronically timed 40-yard dashes in NFL Combine history. Position and year are noted.

Rank	Time	Player	Position	Year
1	4.21	Xavier Worthy	WR	2024
2	4.22	John Ross	WR	2017
3	4.23	Kalon Barnes	RB	2022
4	4.24	Chris Johnson	RB	2008
4	4.24	Rondel Melendez	WR	1999
6	4.26	Dri Archer	RB	2014
6	4.26	Tariq Woolen	CB	2022
8	4.27	Marquise Goodwin	WR	2013
8	4.27	Stanford Routt	CB	2005
10	4.28	Jacoby Ford	WR	2010
10	4.28	DeMarcus Van Dyke	CB	2011

Every time listed is from the official Combine’s electronic timing system. The list is filled with receivers and cornerbacks, the positions where pure speed most directly translates to the field.

The near-misses and the 4.24 club

Below Worthy and Ross, the times cluster tightly. Kalon Barnes clocked 4.23 in 2022, and Chris Johnson’s 4.24 in 2008 preceded one of the best speed-driven careers on the list, including a 2,000-yard rushing season. Rondel Melendez matched that 4.24 way back in 1999, the very first year of electronic timing, a mark that held near the top for a decade. Johnson’s rushing production connects him to leaderboards like the most rushing yards of all time.

Why hand-timed legends do not count

Older, hand-timed sprints float around football lore, most famously Bo Jackson’s reported 4.12 at the 1986 Combine and Deion Sanders’s blazing runs. Hand timing, started and stopped by a human thumb, tends to produce faster numbers than electronic systems, so those marks are not part of the official record. That is why the recognized list begins in 1999. For a look at raw human speed at its absolute limit, see our leaderboard of the fastest man in the world.

Why the record matters

The 40-yard dash is a snapshot of explosive speed, and record-setting times can transform a prospect’s draft night. But football is not a track meet, and many of the fastest runners never became stars, while plenty of greats posted ordinary times. The drill measures one elite trait, not the whole player, a caveat that also applies to feats like the longest field goal in NFL history, where technique matters as much as raw power.

The short version: Xavier Worthy holds the NFL Combine record with a 4.21-second 40-yard dash in 2024, ahead of John Ross (4.22) and Kalon Barnes (4.23). As of the 2025 season, no one has run faster under the Combine’s electronic timing.
