Juventus have received a major boost with the news that Diego did not suffer a serious injury during Saturday's 2-0 Serie A victory over Lazio.
The Brazilian playmaker, who joined the Turin club in a €20million deal from Werder Bremen in the summer, picked up a serious looking thigh injury.
However, a series of scans have revealed no major problem and Diego could now be back in action within seven days.
"The tests done on Diego have not shown any tendon or muscular lesion in his thigh," read a club statement. "He is suffering from muscular fatigue and will need seven days to recover."
Diego will definitely miss Tuesday's Champions League opener against Bordeaux.
Cagliari have denied reports suggesting that they have agreed to sell goalkeeper Federico Marchetti to AC Milan.
Sporting director Francesco Marroccu insists there is no verbal agreement with the Rossoneri that would allow then to have first bargaining rights for the shot-stopper.
Marroccu was quoted as saying: "It's not true that we have promised Marchetti to Milan at the end of the season.
"However, it is true that clubs like Milan, Inter and Juventus wouldn't mind a keeper with Marchetti's quality.
"It will be difficult to hold onto him at the end of the season even though he is doing well here, and he has improved plenty over the last year."Reuse content
