London Broncos have announced their Challenge Cup match against Keighley Cougars and future Behind Closed Doors matches will take place at Rosslyn Park.
The Broncos are currently using Rosslyn Park as a training base, and will now use their ground instead of Ealing Trailfinders.
Talks are also ongoing over a potential groundshare with League One football side AFC Wimbledon, at their new Plough Lane stadium.
An update over talks is expected in the coming days.
Head Coach Danny Ward told the club website: “It can only be a positive for us to be able to play there. It is our training pitch and our first team base, so to be able to play on this surface could be a big advantage for us.”
