Oliver Torres, the Atletico Madrid youngster on loan at Porto, suffered a shoulder injury in the club’s Champions League draw with Basel.
Marca reports Oliver as having to be withdrawn 68 minutes into the 1-1 tie with the Swiss side, but it’s not known the extent of the problem.
“Oliver has a shoulder injury. It was the bad news of the game, but hopefully it’s not serious,” said Porto Coach Julen Lopetegui.
The 20-year-old landed heavily on his shoulder, Marca adds, and has had problems with the joint before, sparking fears of a repeated injury.
