Barcelona defender Carles Puyol is doubtful for Sunday's Primera Division game against Malaga after bruising his leg on Wednesday.
The 35-year-old club captain was substituted after 57 minutes of Barca's 4-1 Copa del Rey victory at Levante after clashing with striker David Barral.
A statement published on Barcelona's official website on Thursday said club doctors had examined the knock to Puyol's left leg before discovering the bruising that will make his participation against Malaga at the Nou Camp unlikely.
Javier Mascherano, who replaced Puyol at Levante, could deputise for the veteran centre-back as reigning champions Barca look to win a La Liga game for the first time in three attempts.
The Catalan club are currently tied with Atletico Madrid for the championship lead after 20 games.
