There’s no real way for the NFL Scouting Combine to measure toughness, but if it could, Jeff Okudah would receive a passing grade.

On Sunday, Okudah took to the field to participate in position drills with fellow defensive backs, trying to prove that he’s still the top cornerback available in this year’s NFL Draft. All was going well until the former Ohio State star had an awkward fall after attempting to catch a football at its highest point during a position group drill.

Okudah’s head appeared to smack the turf at Lucas Oil Stadium, cutting his position group drills short. But it wasn’t the end of the day for the former Buckeye.

Shortly after the tumble, Okudah tweeted out that he was fine, and proceeded to participate in the vertical and broad jumps — posting pretty good marks in both exercises, too.

Okudah posted a 41-inch vertical jump, the best among cornerbacks at the combine. His broad jump came in at 11-feet-3-inches, as well. Not bad after a scary injury.

Heading into the combine, Okudah was regarded as the top cornerback available in this year’s draft, and was considered a top five pick. He’s only solidified that this week.
