Washington wide receiver John Ross ran 4.22 seconds for the 40-yard dash at the NFL combine. If the time is officially confirmed, Ross would break Chris Johnson's 4.24 NFL Combine record from 2008.

Earlier in the week, Adidas was offering to buy an island to any NFL prospect that broke Johnson's record while wearing the 2017 Adizero 5-Star 40 cleats. The player also has to agree to endorse the company's shoes for the 2017-18 season. Ross was wearing Nike cleats and signed with the sportswear giant shortly after the run.

"I can't swim that well,” Ross said of why he didn't run in Adidas cleats. “And I don't own a boat."
