Every year at the NFL Scouting Combine, Rich Eisen of NFL Network runs the 40-yard dash ... in his suit. He does so to benefit St. Jude Children's Research Hospital. You can donate to the cause here at NFL.com.

This year, Eisen's 40-time was clocked at 5.97 seconds, which was his second-best time ever and the second time he completed the run in under six seconds since he started the annual tradition in 2005. His best time came in 2016 when he clocked in at 5.94 seconds. Eisen's run has helped raise over $650,000 for St. Jude's.

NFL Network and companies like AT&T, Marriott, and Under Armor each contributed this year to St. Jude's on behalf of Run Rich Run. As a surprise, New England Patriots head coach Bill Belichick surprised Eisen and Mike Mayock in the NFL Scouting Combine broadcast booth to donate to the cause.

"What you've done with this event has been amazing," Belichick told Eisen.

59-year-old NFL commissioner Roger Goodell ran a 5.41-second 40 on Monday in the league's New York City-based headquarters.

San Francisco 49ers general manager John Lynch also got into the action.

"Rich Eisen and everybody at St. Jude's," Lynch said in the video posted on Twitter, "I want to thank you Rich for making a fool of yourself every year in the name of a great charity. I'm going to sprint my way, along with the 49ers, back out west out of Indy."
