There was a hidden spectator of the NFL match between the Baltimore Ravens and Tennessee Titans in London on Sunday: artificial intelligence. As crazy as it may sound, computers have now been taught to identify on-field head impacts in the NFL automatically, using multiple video angles and machine learning. So a process that would take 12 hours – for each game – is now done in minutes. The result? After every weekend, teams are sent a breakdown of which players got hit, and how often.
This tech wizardry, naturally, has a deeper purpose. Over breakfast the NFL’s chief medical officer, Allen Sills, explained how it was helping to reduce head impacts, and drive equipment innovation.
