On July 3, in the FIFA World Cup Round of 16, Portugal defeated Croatia 2-1. In the injury time of the second half, Croatia scored a "leveling" goal, but due to Pasalic being offside, the goal was disallowed. After the match, FIFA officially explained the reason for the disallowed goal and the technical images provided by VAR via social media.

FIFA officially stated: "Data provided by Connected Ball Technology, embedded in the Adidas Trionda – the official FIFA World Cup match ball – confirmed that Croatia's #20, Igor Matanović, touched the ball during his team's goal against Portugal, allowing the referee to accurately determine offside and disallow the goal."

"The Inertial Measurement Unit (IMU) sensor embedded in the Trionda can detect any subtle ball contact, which is presented as a 'heartbeat waveform' in the broadcast, providing unprecedented data support for referees to help them make quick and accurate decisions."
