Hamiso Tabuai-Fidow's blinding pace is evident, but reports the Cowboys youngster knocked off Josh Addo-Carr as the game's fastest man are incorrect.
The 18-year-old winger dropped jaws in a 31-30 loss to the Rabbitohs on Saturday when he caught teammate Scott Drinkwater's cross-field kick and hit the gas to score a stunning try.
It was reported Tabuai-Fidow had clocked a top speed of 39km/h during that run - which would have eclipsed Storm flyer Josh Addo-Carr's Telstra Tracker record of 38.5km/h in 2019.
In fact, Telstra Tracker GPS data recorded Tabuai-Fidow's top speed as 34.9km/h - only the third-highest speed of round 14.
Raiders halfback George Williams (35.1km/h) and Broncos centre Kotoni Staggs (35) finished ahead of the Hammer.
Titans fullback AJ Brimson equalled his speed and Canberra back Nick Cotric (34.7) wasn't far behind.
South Sydney's Alex Johnston and Brisbane's Xavier Coates jointly hold the 2020 speed title after they each reached 36.9km/h in round six.
In other Tracker categories, Sharks fullback Will Kennedy drew level with Clint Gutherson for the most high-speed efforts (bursts of 20km/h or more) this season with 45 against the Titans.
Brimson came second with 35 high-speed efforts, followed by Parramatta's Blake Ferguson (34), Newcastle's Enari Tuala (34) and Gutherson (33), who has made the top five three weeks running.
Knights captain Mitchell Pearce covered the most distance with 9.9km, just ahead of the underrated Kennedy (9.8), Gutherson, Kalyn Ponga and Sharks hooker Blayke Brailey (all 9.6).
