Argentina's captain Juan Martin Fernandez Lobbe has been ruled out of his side's European tour after injuring himself playing for Toulon.
Lobbe fractured his elbow in the Top 14 clash with Toulouse and is expected to be out of action for the next few months.
"He will soon consult a Marseille professor for an operation," a statement on the Toulon website said. "His unavailability is estimated at two to three months."
