The pint-sized attacker, who made his first league appearance for the Bianconeri since rejoining his boyhood club, picked up the knock against his former employers on Saturday
The 25-year-old, whose co-ownership status with Parma was resolved in favour of the Italian champions over the summer, picked up the knock in the Old Lady's league opener against the Gialloblu.
A medical examination has revealed a first-degree sprain combined with damage to the anterior ligament of Giovinco's left ankle, after he was stretchered off during the match following a strong challenge from Graziano Pelle.
Recent diagnosis has slated the recovery period to revolve around a two-week span, ruling the Italy international out of Cesare Prandelli's plans ahead of the Azzurri's next World Cup qualifying fixtures against Bulgaria and Malta.
Giovinco is now expected to return to action in time for Juve's meeting with Genoa on the third matchday of Serie A.
