Roma will reportedly be without Michael Bradley for the next month after he picked up an injury on international duty.
The American suffered an ankle problem in the game against Costa Rica which didn’t cause too much concern initially.
However, tests have shown ligament damage which is likely to see the midfielder sidelined for around four weeks.
The 2012 summer signing from Chievo Verona will subsequently miss the Rome derby against Lazio on September 22.
