Glamorgan Wanderers will start life in the SWALEC League Division One East in 2011-12 with a home match against fellow fallen giants Ebbw Vale following their relegation from the Premier Division.
With another former Premier club in Newbridge also in One East the race for the top spot in the division should be very intense.
Wanderers head coach Chris Ower said, "It's great to be starting the season with such a competitive fixture. Ebbw Vale will have big ambitions for this season and after losing to us in the first of our play-offs at the end of last season, I'm sure they'll feel they have an opportunity to get one back on us very quickly.
"They are a very good side, but having said that, I'm pleased with our squad at this point in time. We have a number of players with Premiership experience, mixed with some exciting young players so I'm confident we will be able to challenge for a Champions League place, and even the Division One East title this season.
"Ultimately our aim is to work towards getting back into the Premiership within around three years and as a club, we have put a number of building blocks in place to progress at a sensible pace."
