Welsh hooker Gerwyn Price has returned to Cross Keys in Wales, after spending the last month with the Warriors.
He was brought in on a short-term deal, with Pat MacArthur and Dougie Hall on Scotland duty and Finlay Gillies and Fergus Scott both out injured.
Price started in the 36-20 win away to Zebre and came on as a replacement in the record 60-3 victory over the Dragons at Rodney Parade last month.
Gregor Townsend said: "We'd like to thank Gerwyn for coming in and helping us out when we had some injuries and players away with Scotland.
"He has contributed to what has been an exceptional team effort over the last few weeks, and we wish him all the very best for the future."
