Barcelona have revealed that Spanish midfielder Sergi Roberto will miss the next "seven to 10 days" after picking up a groin problem in Tuesday's 2-0 win over BATE Borisov in the Champions League.
Roberto started the European fixture in a midfield three with Sergio Busquets and Javier Mascherano, but pulled up with an injury in the 17th minute of action, which forced him off the field.
After undergoing an examination on Wednesday morning, Barcelona have confirmed the extent of the damage.
"Tests on Wednesday morning reveal that first team player Sergi Roberto has pulled an adductor tendon in his left groin. He is expected to be out of action for seven to 10 days," read a statement on Barcelona's website.
The 23-year-old has already made eight starts for Barcelona this season, including six in La Liga.
