Goal-line technology provider Hawk-Eye on Tuesday apologized to Huddersfield after Japan defender Yuta Nakayama was denied a goal during the team's 1-0 home defeat to Blackpool in the English second-tier Championship.

Nakayama appeared to have bundled home the leveler during the second half on Sunday only for the on-pitch match officials, who were unsighted and unable to confirm the goal, to wave play on.

Normally, referees are notified on their watch if the Hawk-Eye system detects the ball crossing the goal line.

"Hawk-Eye can confirm that the ball was obscured from the Goal Line Technology cameras as it moved over the line," a statement from the company read.

"The position of the players, the goal post and the goalkeeper impacted the camera's line of sight to the moving ball, and as such, a decision could not be determined by the system."

The company apologized to both the English Football League and Huddersfield for the technical failure.

The EFL said it is "incredibly frustrated" but "the referee's decision is final and the match result stands."
