Arizona Cardinals might just have the fastest player in the NFL, after Robert Gill posted an incredible training camp video where he is filmed running on a treadmill at 25mph.
The 29-year-old wide receiver recently signed a three-year contract with the National Football Conference franchise after demonstrating his exhilarating speed and explosive power - which is on show again in this crazy clip.
As the oldest rookie on the NFL roster, you could be forgiven for thinking that Gill's chance of forging a professional football career had passed him by. But, then again, not everyone can run a 40-yard dash in 4.19 seconds.
