Reinildo started the victory over Athletic Club pre-international break, but during a match with Mozambique, he suffered a gruesome shin injury after collided with the post after making a goal-saving clearance.
As per Diario AS, Reinildo will be tested upon his return to Atleti, but for now, his availability against Valencia is in doubt.
Reinildo being unavailable would be a blow for Atletico Madrid, but not a major one. It could allow Clement Lenglet to make his debut, as he has yet to feature since joining from Barcelona during the final days of the summer transfer window.
