Atletico Madrid's Fernando Torres appears set to miss Sunday's game against Osasuna after suffering a hip injury.
The former star striker has only made two starts in La Liga this season, and his club said he will be training on his own over the weekend.
An Atletico statement read: "The MRI which Fernando Torres has undergone in Majadahonda's FREMAP Clinic has confirmed that the striker from Madrid suffers a muscle injury in the internal obturator muscle of the left hip.
"Pending evolution, Torres will receive physical therapy treatment and will do alternative training for the next days."
Atletico trail La Liga leaders Real Madrid by nine points and are in sixth place.
