Shedrick Jackson was unfazed when asked about his unofficial time in the 40-yard dash at Auburn’s pro day.

The former wide receiver, without hesitating, simply said he was “not surprised” that he clocked a 4.25 on Tuesday afternoon inside the indoor practice facility at the new Woltosz Football Performance Center.

“It was a good feeling,” Jackson said. “Feel like I could have did a little bit better, but it’s decent.”

How 14 former Auburn players performed at 2023 pro day

Decent was an understatement when it came to Jackson’s showing at pro day. The 6-foot-1, 193-pounder turned in the most impressive performance of the day among the 14 former Tigers who officially partook in the showcase in front of personnel from all 32 NFL franchises, as well as a few from the CFL.

Along with his blazing time in the 40, Jackson recorded a 38.5-inch vertical and an 11-foot-2 broad jump, along with 13 reps of 225 pounds on the bench press.

Jackson’s 40 time, while unofficial and hand-timed by the scouts in attendance, would have been tops among all players at this year’s NFL Combine, regardless of position. The fastest time posted a a few weeks ago in Indianapolis, where all runs are laser-timed, was a 4.26 by Michigan cornerback D.J. Turner II. The fastest time by an offensive player at the combine was the 4.32 posted by Texas A&M running back Devon Achane, while the fastest time by a wide receiver was 4.33 by Nebraska’s Trey Palmer.

Only three players have run a faster 40 time at the combine all-time: former Washington receiver John Ross (4.22) in 2017, former Baylor corner Kalon Barnes (4.23) in 2022, and former East Carolina running back Chris Johnson (4.24) in 2008.

Jackson’s 38.5-inch vertical jump would have tied for 12th among wide receivers at this year’s combine, joining North Carolina’s Josh Downs and Michigan’s Ronnie Bell, while his 11-foot-2 broad jump would have tied for the second-best mark among receivers. Liberty’s Demario Douglas and TCU’s Quentin Johnston both posted that same distance, while Tennessee star Jaylin Hyatt set the bar with an 11-foot-3 broad jump in Indianapolis.

“I’m a competitor,” Jackson said. “I want to be the best and I work at it every day. I try to stay locked in and do what I know I can do and just always reach for new goals.”

After catching just 66 passes for 874 yards and one touchdown over his five seasons at Auburn, Jackson hopes his performance at pro day — which included running routes for and catching passes from Newton, the 2015 NFL MVP and former Heisman winner — was enough to warrant some additional attention from an NFL franchise.

“I think I was decent today,” Jackson said. “I’ve got more to show. I’m not done yet. I’m not on a team, and I’m not satisfied with that.”
