Aston Villa centre-back Diego Carlos is set for a period on the sidelines after rupturing his Achilles in his home debut against Everton on Saturday.
The 29-year-old summer signing was forced off in stoppage time in Villa's 2-1 victory over Everton .
Carlos joined from Sevilla for £26m in June and started both of Villa's opening Premier League fixtures.
"The player will require surgery and will then begin his rehabilitation programme," a club statement confirmed.
Following the game, Aston Villa boss Steven Gerrard admitted he was "extremely worried" about the Brazilian defender after his injury.
