London Irish are “getting close” to confirming their return to the capital.
Chief executive Brian Facer says the club, who are bottom of the Premiership, are looking at “serious alternatives” to Reading’s Madejski Stadium, their home since 2000.
A ground-share at Brentford FC’s new Lionel Road stadium in west London appears to be the preferred option.
“Whatever we do, it will be done with proper grounding and proper backing,” Facer told BBC Sport.
Brentford want the 17,250-seat Lionel Road stadium ready by December 2019 after revised plans forced them to postpone the start of construction.
