Inter defender Lucio is facing a race against time after being included in Leonardo's squad for their Champions League clash at Bayern Munich on Tuesday.
It was feared the Brazilian would be ruled out from the second-leg, last 16 clash, with a hamstring injury he sustained in Friday's 1-1 draw with Brescia, but there are hopes he could recover in time to play a role in Germany.
Lucio was in the gym during Sunday's final training session before they fly out to Germany tomorrow.
Diego Milito, Walter Samuel and David Suazo will stay behind as they are all injured and will continue specific rehabilitation programmes, Inter's official website confirmed on Sunday.
Maicon has a fever, but he is expected to recover in time, while Andrea Ranocchia is nursing a knock, but remains in contention.
Bayern lead 1-0 on aggregate following their win at San Siro three weeks ago.
