Roma have breathed a sigh of relief as Francesco Totti looks as though he is fit for the derby.
The talismanic captain strained his groin earlier in the week and was a doubt for Sunday's match.
However, Totti trained fully this afternoon and is expected to start against Lazio.
The 34-year-old has missed two derbies already this season through suspension and injury.
In other news, Marco Cassetti has been ruled out of the fixture after developing a muscle problem.
It's thought that Vincenzo Montella will deploy Nicolas Burdisso as cover in the full-back position.
