The Football League have revealed goal line technology will be used at the League One play-off final at Wembley on Sunday - the first time it has been used at a Leyton Orient game.
Goal line technology was only introduced in the Premier League at the beginning of the 2013/14 season but was not introduced in the Football League.
However, the Hawkeye Goal Decision System will be used at all three Football League play-off finals this Bank Holiday weekend - including the O's clash with Rotherham United on Sunday.
The Football League's Chief Operating Officer, Andy Williamson, told the Football League website: "It will be another historic moment for The Football League when goal line technology is used in a Play-Off match for the first time.
"The Football League has long been a supporter of technology and innovation. Although it is not practical to provide it across all League grounds at the current time, when the technology is there we will always look to use it."
