The 23-year-old has agreed a deal until the end of the season and will help alleviate the loss of South African Jacques Vermeulen, who is set to be out until the New Year after suffering a setback in his recovery from a serious hamstring injury.
The back-row forward, who has won a handful of caps for his country, will join up with the Chiefs following the current Autumn Nations Series, where he is currently in camp alongside fellow Exeter player, Facundo Cordero.
Standing at 6ft 6ins and topping the scales at 106kg, Grondona will offer a sizeable option for Chiefs Director of Rugby, Rob Baxter, in his back-row options.
Born in Buenos Aires, Grondona started his rugby career with the Champagnat club, before being part of the Jaquares squad, where he has featured previously in Super Rugby.
In December of last year, Grondona – along with compatriot Mateo Carreras signed for Newcastle Falcons – but his time in the North East was cut short after he sustained a serious knee ligament injury in training.
Now fully fit, Grondona is hoping his Premiership experience lasts a little longer in the Westcountry, having put pen to paper on the move to Sandy Park.
