Barcelona remain unsure of when captain Andres Iniesta will return to action, despite returning to light training on Wednesday.
The Spanish international was forced off after just 34 minutes in the 1-0 win over Atletico Madrid on Sunday with a hamstring injury in his right leg.
Initial reports had claimed Iniesta would miss around a month of action for the Catalan giants, but a statement from Barca on Wednesday afternoon confirmed there is no timescale on his return.
If Iniesta is ruled out for the expected full month, the 33-year-old will miss his side’s games with Malaga, Athletic Club, Sevilla and the Champions League second leg with Chelsea.
The upcoming international friendlies for Spain, who face Germany and Argentina later this month – are expected to be missed by the experienced midfielder, who will be rested for the summer World Cup in Russia.
Barca are on course to win the La Liga title having beaten Diego Simeone’s Atleti at the weekend thanks to a superb free-kick from Lionel Messi.
Ernesto Valverde’s side now sit eight points clear at the top of the league standings and remain set for a potential treble, being in the Copa del Rey final and in the Champions League.
