Captain want to be in the front line battling for a place in the Coppa Italia final
The captain is still suspended for kicking Mario Balotelli in last year's 1-0 loss in the final against Inter.
Totti was handed a four-game ban, and has one more match to serve before he can return.
"It's a shame I am out at such an important moment. I wanted to be there but the episode which happened means I am still suspended for another game," he told Sky Sport 24.
"But I hope to see Roma reach the final."
'Er Pupone' then turned his attention on league matters where fourth place is still possible.
"It's all open for fourth. There are two games left and we are two points behind Udinese. But it will be very difficult," he said.
The Giallorossi are 1-0 down heading into the second-leg at San Siro.
