Madrid, Jan. 22 -- FC Barcelona's vital Champions League win at Slavia Prague on Wednesday night came at a cost with the news that midfielder Pedri suffered a hamstring injury.

The Spain international limped out of the 4-2 win in the 61st minute to be replaced by Dani Olmo, with early tests indicating that he could be out of action for at least three weeks.

That means he will miss league matches against Oviedo, Elche, and Mallorca, the Copa del Rey quarterfinal away to Albacete and the first leg of a possible semifinal the following week, as well as next week's Champions League game at home to Copenhagen.

The injury adds to Barcelona's problems, with Ferran Torres, Gavi, and Andreas Christensen also sidelined.

The situation is even more...
