Barcelona confirmed on Saturday that Messi will miss the next three weeks after fracturing his arm against Sevilla.
The captain was forced off in the first half in obvious pain and is now set for a spell on the sidelines.
The injury comes at a foul time for Barcelona with entomb Inter Milan within the Champions League up next followed by El Clasico.
Messi will miss both matches as well as the Copa del Rey game against Cultural Leonesa (which he would have probably weekday out anyway), the trip to Rayo Vallecano and therefore the come Champions League fixture against entomb Inter Milan.
Barcelona are going to be hoping he may create it back in time for the sport against Real Betis on Nov eleventh and positively for the trip to the Wanda Metropolitano to take on Atletico on November 24th.
