Juventus centre-back Giorgio Chiellini is facing at least two weeks on the sidelines after suffering an injury on Friday.
The Italy international suffered a strain to the collateral ligament of his right knee during a friendly with Lumezzane.
The 28-year-old will now miss Monday's Serie A clash with Lazio and potentially the visit of AC Milan on April 21st.
The injury marks another setback in what has been a frustrating season for Chiellini, who has also been troubled by calf and ankle injuries.
Juve are on course to lift the Serie A trophy this season, sitting nine points clear at the top of the table.
