Lionel Messi tore his left hamstring on Nov. 10 and had been in his home country recovering since Nov. 29.
Barcelona F.C. also says that goalkeeper Victor Valdes has been given the go-ahead by team doctors to return.
Valdes looks set to start for Barcelona F.C. in Sunday's home Spanish league match against Elche for his first action in six weeks since hurting a right leg muscle while playing for Spain in a friendly at South Africa.
Barcelona F.C. had its only two losses so far this season playing without Messi and Valdes.
Barcelona F.C. leads the Spanish league along with Atletico Madrid.
