Argentina utility back Juan Martin Hernandez will miss the Rugby World Cup after failing to recover in time from a right knee injury.
Pumas coach Santiago Phelan today unveiled his 30-man player list to play in New Zealand and confirmed Hernandez will not be there.
Hernandez suffered his injury in March, playing for French club side Racing Metro against Bourgoin.
He underwent surgery and began an intensive rehabilitation process in the hope of recovering in time for the World Cup.
