Exeter Chiefs have recalled Henry Slade, Luke Cowan-Dickie, Jake Arnott and Will Carrick-Smith ahead of their LV=Cup fixtures.
The quartet have been on-loan at local Championship club Plymouth Albion, but with international players away Rob Baxter has decided to bring in his young stars for more first team experience.
Plymouth have started the new season well but will be without their quartet of Chiefs for a crucial fixture against London Scottish this weekend.
"Guys like Ben Moon, Chris Budgen and Neil Clark are going to have opportunities to push their claim, as are some of our younger academy guys who, the reality is, we want to see in a first-team shirt, and see what they can do," said Baxter.
"We're in a great position now, we've had a good run of Premiership results, we've had a nice time in Europe and we can give any bumps and bruises a bit of time to freshen up now for the guys not involved in the LV= Cup or away with international sides."
