Babos is one of five changes for Dragons as the team look to finish the campaign with a win at Ystrad Mynach tonight (6pm) after the fixture was switched from Church Bank, Llandovery.
There are four changes in the forwards as a new-look front row sees Scott Evans and Zac Hewlett called up to pack down with Chris Coleman.
James Thomas moves from the back row to the second row, where Max Williams is given a start at lock.
The final change is the selection of Ben Fry at blindside flanker, where he will play alongside captain Lennon Greggains and Taine Basham.
Brodie Coghlan, Ed Scragg, Rob Brookson and Llew Smith are among the new faces called onto the replacements as Dragons look to bounce back from defeat against Leinster A last weekend.
