London Welsh in Aviva Premiership action
London Welsh will begin their campaign to regain a place in the Aviva Prermiership with a clash against Bedford Blues.
The Exiles were relegated from the top flight after just one season and are strongly tipped to bounce straight back in 2013-14.
Bedford lost in last season's play-off final to Newcastle Falcons, who returned to the Premiership as a result.
The new Greene King IPA Championship season begins with a series of double-headers, as London Scottish and Ealing Trailfinders join Welsh and Bedford at Allianz Park in Watford on opening weekend.
There are also double-headers at Castle Park and Sandy Park in Round One (September 13-15).
