AC Milan star Robinho looks set to miss the Serie A clash with Lazio and next week's UEFA Champions League tie against Malaga after picking up a thigh injury.
The 28-year-old Brazilian is suffering from a muscle problem in his right leg and could be out for at least 10 days, according to Sky Sports Italia.
Robinho, who was ruled out for a month earlier in the season with muscle fatigue, is set to have further tests this week.
The former Manchester City player has only made four appearances in Serie A this season, including three from the bench.
Inter Milan president Massimo Moratti admits he has a difficult decision to reach as he considers whether Andrea Stramaccioni should remain as the club's head coach.
