The third Argentinian to join the Arrows for 2021, Cortés arrives from PRO14 club Glasgow Warriors; the prop had signed a short-term loan with the Scottish outfit this past February, but was unable to feature before the season was cut short.
Prior to joining the Warriors, Cortes enjoyed an accomplished career in England; he played 114 games for Bristol over a six-year spell between 2012 and 2018, including winning promotion from the RFU Championship on two occasions. Cortes later moved to Leicester Tigers, where he made 10 appearances for the Premiership club.
The 34-year-old has five caps for Los Pumas, spanning from his debut against Chile in 2011 to his most recent appearance against New Zealand in the Rugby Championship in 2018. He played his grassroots rugby with Cordoba Athletic Club.
