Tottenham have announced plans for the world's first dividing retractable football pitch at their new stadium.
The club's new ground will boast separate playing surfaces for NFL and football.
A grass surface, used for football, will sit on top of an NFL-approved artificial pitch and divide into three pieces.
Each section will roll into place from underneath the South Stand and join together to create a playing surface in a process which is said to take 25 minutes.
The club says the joins in the turf will be "invisible and undetectable".
A statement on the club's website said: "The fully retractable grass surface will be used for football matches whilst the artificial pitch underneath will be used for NFL matches, music concerts and a range of other events, in order to protect the integrity of both playing surfaces.
