Pablo Osvaldo has reportedly not yet returned to Southampton for pre-season training following the summer break.
The striker, who spent the second half of last season on loan with Juventus, was due to join up with the squad earlier this month.
However, the Daily Echo reports that the 28-year-old still has not returned to the club, having produced a doctor's note to exclude him from training.
Osvaldo has been linked with a move away from St Mary's this summer.
