Club colleague Henry Purdy is named on the wing for England after also starting the 16-15 defeat by Ireland in Athlone a fortnight ago.
The inclusion of Wells in the back row is one of just two alterations to the starting line-up after that defeat, with hooker Nathan Morris also gaining a call-up.
England Under-20s host France Under-20s at Worcester on Saturday. Kick-off is at 3pm, with live coverage on RFU.com, http://www.rfu.com/rbssixnations/live-streaming.
