Munster have recruited the services of full-back Lucas González Amorosino and flanker Sean Doyle on short-term contracts.
Argentinian international Amorosino and Australian-born Doyle have both signed three-month contracts with the province.
Amorosino, who is currently involved in Los Pumas' World Cup campaign, will start in Friday night's Bronze medal match against South Africa.
The full-back has just completed a season with Cardiff Blues where he made 12 appearances for the Welsh club.
Prior to that he played for Top 14 sides Oyannax and Montpellier, and Premiership team Leicester Tigers. A former Argentinian Sevens player the speedster is also comfortable playing on the wing and has played 47 times for Argentina, scoring six tries.
Back row signing Sean Doyle arrived on Tuesday and has trained with the squad in Cork.
The 26-year-old joins from Super Rugby outfit the Brumbies and previously played for Ulster, making 24 appearances for the province.
