It’s been like an old Hollywood stare down for months, only the stakes continue to rise for both Noah Lyles and Tyreek Hill.

NFL star Tyreek Hill first challenged Olympic gold medalist Noah Lyles after the Summer Games in Paris. Now the two superstars will battle it out for bragging rights.

Hill has run a 40-yard dash at an NFL workout in 4.29 seconds. Lyles won the 100 meters at the Olympics last year in 9.784.
