Lazio coach Edy Reja says Sergio Floccari has recovered from his spotkick miss in last week's derby.
Floccari missed a penalty with Lazio leading Roma 1-0 before the Giallorossi stormed back to win 2-1.
"Sergio is a very sensitive lad. I was pleased to see the affection that the fans showed to him this week," said Reja.
"It was a heavy blow, but that is over now. The lad has fully recovered and he remains the designated penalty taker."
