Roma playmaker Miralem Pjanic will likely miss the Giallorossi's Champions League opener against Barcelona due to a right calf strain.
Pjanic was injured while playing for Bosnia in a 3-0 win over Andorra on Sunday in a European Championship qualifier. His absence would be a setback for the Italian club after the midfielder's strong start to the season.
Roma says tests Tuesday revealed a first-degree strain and Pjanic's condition "will be assessed over the coming days."
Pjanic will miss Saturday's Serie A match at Frosinone. Roma then hosts defending champion Barcelona at the Stadio Olimpico next week.
Pjanic scored with a curling free kick in Roma's 2-1 win over Juventus last month.
Roma's 38-year-old captain Francesco Totti, who is yet to play this season, will likely replace Pjanic against Frosinone.
