Manchester City striker Craig Bellamy could face a short spell on the sidelines after injuring his knee in Sunday's 1-0 defeat at West Ham United.
The Wales international will see a specialist in London on Monday to assess the injury and seems certain to miss the midweek trip to Aston Villa.
"Craig will see the knee surgeon that he's seen before as he has a bit of pain on his patella," confirmed City boss Mark Hughes after the Upton Park clash.
"We hope it's nothing serious. We don't anticipate that it will be and it'll be checked out on Monday.
"Robinho's gone over on his ankle as well. It's a similar one to when he was injured against Arsenal, it could be the same injury and he could be out for Wednesday as well.
"Micah (Richards) had a stiff hamstring on Saturday, had some work with the physios and it eased off.
"It wasn't an actual pull, but he went into a challenge and felt it stiffen up almost immediately. We hope we can work on it and release the tightness, hopefully it isn't a strain because that would take him out for a number of weeks."
Of his side's defeat, Hughes added: "Goals change games, it's an old cliche but it's absolutely true.
"If we'd scored first West Ham would have had to come out at us, which is when we can pick teams off.
"But when we concede first we find it difficult to put pressure on. Overall the performance was fine but we're very disappointed to lose away from home again."
