Andrews has been named captain of the Ospreys’ 12-man squad for their clash with the Falcons at Coventry’s Ricoh Arena on Saturday.
The Ospreys have made six changes to the squad that defeated the Scarlets and the Dragons in the Welsh leg in Cardiff last month to progress to the final for the first time.
Current Wales 7s international Morgan Williams continues in the squad along with age-grade cap, Joe Gage, the pair having played in all three of the Ospreys’ appearances in the competition.
Bridgend’s Joseph Scrivens and Tom O’Flaherty are named once again alongside David Evans of Aberavon.
Coming into the squad are 19-year old Wales age-grade cap, Matthew Aubrey, experienced Wales 7s international, Chris Knight, Aberavon’s Jonathan Phillips and Andrew Claypole, and Alex Dunham and Mike Sully from Swansea RFC.
Ospreys skipper Andrews said: “There have been a few changes from the Welsh leg but the squad have come together well and we are looking sharp in training.
“Everyone’s looking forward to the weekend and testing ourselves against some very good opposition.”
