The Swedish international completed his transfer to Nou Camp from Inter Milan for 46 million Euros plus the swapping of Cameroon striker Samuel Eto'o on Monday.

However, a broken bone in his left hand will require a surgery that will keep the 27-year-old out of the game for up to 21 days.

"The operation will prevent Ibrahimovic from leaving with the team on Wednesday for the tour of the west coast of the United States," read a statement on Barcelona's website.

Ibra is expected to make his Barca debut when the Blaugrana take on Manchester City in a pre-season friendly on August 19th.
