Barcelona says striker David Villa has been taken to a hospital because of kidney stones.

The club said the 31-year-old Spain forward would be ''subjected to appropriate treatment to eliminate the kidney stones'' in the next few hours.

The club said in a statement Monday that Villa is doubtful for Saturday's league game at Granada .

The Catalan club leads the Spanish league by 12 points ahead of second-place Atletico Madrid, with archrival Real Madrid 16 points behind.

Villa has been given limited playing time this season after returning from a long layoff because of a broken leg.
