Inter Milan's Brazilian defender Lucio could miss Tuesday's Champions League trip to Bayern Munich after being diagnosed with a muscle strain.
He was forced off during Friday night's 1-1 draw at Brescia and may now miss the game against his former team.
Inter are in a precarious situation having lost the first leg at home 1-0.
They are the last remaining Italian representatives in European competition this season.
Having beaten Bayern in the final in Madrid last May Inter are the reigning champions.
