Newcastle have confirmed that they will not fight the decision to allow London Welsh into the Aviva Premiership.
The Exiles won their appeal against the initial decision to block their promotion to the top-flight - with the Falcons being relegated as a result.
Newcastle were believed to be considering a legal challenge against the ruling, however they have now opted to focus on winning promotion back to the top-flight instead.
A statement from the club read: "Newcastle Falcons confirm there will be no appeal of the decision made by the independent panel to uphold London Welsh's appeal and relegate the Falcons to the Championship.
"We are now looking forward to an exciting new era under the guidance of incoming director of rugby Dean Richards."
Newcastle will now kick-off their challenge against Bristol on September 1, with their first home game coming against Doncaster 13 days later.
