Dani Olmo is set to be sidelined for around a month with a shoulder injury.

The Spaniard scored Barcelona's second goal in their 3-1 comeback win over Atletico Madrid on Tuesday, but injured himself in the process.

He was substituted off less than two minutes after his goal, with the club confirming on Wednesday that he had dislocated his shoulder.

"After tests, it has been decided to follow a conservative course of treatment," Barcelona said in a statement on social media.

"Recovery time is approximately one month."

Olmo has scored four goals and provided two assists in 13 LaLiga appearances so far this season.

Only Pedri (30) and Marcus Rashford (24) have created more chances than Olmo's 23, though the 27-year-old has underperformed his 3.2 expected assists (xA).

Barcelona are also currently without Fermin Lopez, Marc-Andre ter Stegen and Gavi through injury, while Frenkie de Jong was absent against Atletico due to illness.
