Argentina international out of international friendlies as Ligue 1 side are dealt an early injury blow, with the striker possibly out for a number of weeks
The Argentina international is likely to be out for several weeks after the club announced he sprained his ankle at the Stade Gerland.
"Lopez suffered a sprained left ankle and will require further tests to determined the extent of his injury," read a statement released by the club.
Lopez went to ground heavily following a strong challenge from Montpellier's Vitorino Hilton and he had to be stretchered off.
It is not the news coach Claude Puel was hoping for. The Lyon captain was set to play for Argentina in their friendly games against India and Bangladesh next month, but is almost certainly out of both matches.
