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.
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.
Gerrard partnered Carlos with Ezri Konsa in central defence against Bournemouth, before playing him with the recalled England international Tyrone Mings against Everton.
