Argentina internationals Agustin Creevy and Ignacio Mieres are to join Worcester next season, the English Premiership club announced Wednesday.
Creevy, a 27-year-old hooker, will arrive at Sixways after the end of the European season from French club Montpellier while 25-year-old fly-half Mieres will join from Premiership rivals Exeter.
The 22-times capped Creevy previously played in France for Biarritz and Clermont and Worcester director of rugby Richard Hill was delighted to have him coming to Sixways.
"Agustin is a quality international player who will add real strength in depth and power to the pack of forwards we are building here at Warriors," Hill said.
"We have signed a very passionate rugby player whose attitude and dedication is superb," added Hill, whose side are currently ninth in the 12-team Premiership but 15 point clear of bottom-of-the-table Sale, who currently occupy the lone relegation place.
Turning to Mieres, who has won six caps for the Pumas, Hill, who had already agreed a deal for Argentina's Leonardo Senatore, said: "Ignacio is a superb goal-kicker with a very high percentage of success who is very ambitious and keen to join us.
"Last season he started the vast majority of games for Exeter as they were very successful and secured a top six finish and with it Heineken (European) Cup rugby.
Exeter coach Rob Baxter was sorry to see Mieres on his way out of Sandy Park but said he understood why the Pumas' playmaker wanted to move after falling behind Irishman Gareth Steenson in the race to be the club's starting fly-half.
"Nacho is wanting to play more rugby, get more starts, and right now he is feeling that will happen more often at another club," explained Baxter of a move that will see Mieres leave with a year still left on his Exeter contract.
