The Germany striker has been sidelined for five months after injuring his knee but is ready to make his return against Udinese in the Coppa Italia semifinal second leg.
The attacker has been sidelined for around five months since injuring his left knee in the Cagliari clash in September but returned to training last week and is now in contention for a starting spot on Tuesday.
Gomez was the Viola's marquee signing from Bayern Munich in the summer, joining the Florence-based outfit for a reported 20 million euro, but has hardly kicked a ball for Vincenzo Montella's men after the setback in the third league game of the season.
If the 28-year-old does not see action against the Zebrette, then he is likely to face Inter in Serie A on Saturday.
Fiorentina trails Udinese 2-1 from the first leg and will already be without Italy international Giuseppe Rossi after he injured his right knee in January.
Gomez has made only five first-team appearances since signing for the club last summer.
