2025 NFL Scouting Combine: Top 10 fastest 40-yard dash times for cornerbacks

Day 2 of workouts at the 2025 NFL Scouting Combine got underway Friday with the cornerbacks. They were the first group of defensive backs to take the field at Lucas Oil Stadium, and the Top 10 fastest 40-yard dash times out.

Kentucky’s Maxwell Hairston stole the show with a 4.28-second 40-yard dash on his second attempt. That put him at No. 5 among the all-time fastest cornerbacks in Combine history and just outside the Top 10 fastest times ever recorded at the event. Iowa State’s Darien Porter also hit 4.30 seconds on his first attempt.

There were some other impressive times, as well, including Tulane’s Caleb Ransaw and Kansas State’s Jacob Parrish. Here are the fastest 40-yard dash times for cornerbacks at the 2025 NFL Scouting Combine.

1. Maxwell Hairston, Kentucky – 4.28 seconds

Before Maxwell Hairston got to the starting line for his 40-yard dash, NFL Network’s Daniel Jeremiah said he could be the fastest player at the Combine. With a 4.28-second run, he showcased his speed in front of a slew of NFL personnel.

Hairston appeared in seven games this past season at Kentucky, but made his mark in 2023 as a sophomore. He set career-highs with 60 tackles, two tackles for loss and an SEC-leading five interceptions to anchor the defense.

2. Darien Porter, Iowa State – 4.30 seconds

As a sixth-year player at Iowa State in 2024, Darien Porter had the best year of his career. His speed was a big reason why, and he showcased it with a 4.30-second 40-yard dash at the 2025 NFL Scouting Combine.

Porter had a strong final season in Ames to anchor the Iowa State defense. He totaled 18 tackles, two tackles for loss and the first three interceptions of his career, and will now look to take his talents to the next level.

3. Caleb Ransaw, Tulane – 4.33 seconds

After three years at Troy, Caleb Ransaw continued to be a dominant playmaker at Tulane this past season. He showcased his big-time speed, as well, with an impressive 4.33-second 40-yard dash at the 2025 NFL Scouting Combine.

Ransaw had 34 tackles, four tackles for loss and a sack with the Green Wave in 2024. That came after a huge 2023 campaign at Troy when he had 51 tackles, six tackles for loss and an interception as a junior.

4. Jacob Parrish, Kansas State – 4.35 seconds

Another impressive time at the 2025 NFL Scouting Combine, Jacob Parrish broke 4.40 seconds. He cam in at 4.35 seconds to become one of the Top 10 fastest cornerbacks in the 40-yard dash.

5. Zah Frazier, UTSA – 4.36 seconds

One of the big risers after the 40-yard dash, Zah Frazier impressed with his run. He came in at 4.37 seconds to sit among the Top 10 cornerbacks at the 2025 NFL Scouting Combine.

Frazier had a breakout junior season at UTSA before declaring for the draft. He had 24 total tackles and six interceptions to anchor the Roadrunners defense.

T-6. Jahdae Barron, Texas – 4.39 seconds

After winning the award for best defensive back in college football in 2024, Jahdae Barron will look to make a similar impact at the next level. He had a solid time in the 40-yard dash, as well, at 4.39 seconds.

Barron was the focal point of Texas’ defense this past season as the Longhorns made a second straight College Football Playoff semifinal. He had a career-high five interceptions in 2024, and totaled eight picks – including one pick-six – and 20 tackles for loss across a huge three-year run to finish his career.

T-6. Robert Longerbeam, Rutgers – 4.39 seconds

After his first attempt, Robert Longerbeam found himself outside the Top 10 fastest cornerbacks at the 2025 NFL Scouting Combine. However, he impressed on his second go-round, hitting 4.40 seconds to break through.

Longerbeam spent five years at Rutgers, including four as a starter. As a fifth-year senior in 2024, he had a career-high 45 tackles to go with two tackles for loss and two interceptions to anchor the Scarlet Knights’ defense.

8. Justin Walley, Minnesota – 4.40 seconds

A four-year starter at Minnesota, Justin Walley only appeared in 10 games in 2024. Still, his production was impressive, as was his 4.40-second 40-yard dash at the 2025 NFL Scouting Combine.

Walley had 42 tackles, two tackles for loss, a sack and two interceptions as a senior with the Golden Gophers. All told, he had 155 tackles and seven picks – including his first career pick-six this past year.

9. Mac McWilliams, UCF – 4.41 seconds

After four years at UAB, Mac McWilliams entered the transfer portal and headed to UCF. He’s now looking to head to the NFL, and his 4.41-second 40-yard dash put him in the Top 10 among cornerbacks at the 2025 NFL Scouting Combine.

McWilliams totaled 32 tackles and a career-high seven tackles for loss in his lone season at UCF in 2024 while adding one interception. That came after four years at UAB where he had 101 tackles, six tackles for loss and a pick during that time.

T-10. Bilhal Kone, Western Michigan – 4.43 seconds

After starting his career at FCS Indiana State, Bilhal Kone spent two years at Western Michigan. He became one of the top cornerbacks in the MAC, and his 4.43-second 40-yard dash put him in the Top 10 at the position at the 2025 NFL Scouting Combine.

Kone saved his best season for last. He totaled 70 tackles in 2024 with one tackle for loss and an interception before declaring for the NFL Draft.

T-10. Trey Amos, Ole Miss – 4.43 seconds

An important part of the Ole Miss defense this past season, Trey Amos got into the 10 fastest times for cornerbacks when the official times came down. He logged a 4.43-second 40-yard dash.
