Goal-line technology provider Hawk-Eye has apologised to Huddersfield and the English Football League (EFL) after the failure to award a goal to the Yorkshire side on Sunday despite the ball crossing the line.
The Terriers' Yuta Nakayama was denied an equaliser in the Championship match against Blackpool after the technology failed to send a signal to the watch of referee John Busby to alert him to the ball being over the line.
The official and his assistants, who were unsighted, also failed to spot the ball had gone in.
The EFL issued a statement on Monday stating it was 'incredibly frustrated' the goal had not been awarded, and on Tuesday Hawk-Eye provided an explanation for the failure of the technology.
