Carlos Tevez will miss Manchester City's Premier League fixture with Arsenal on Saturday but Robinho may recover from his own injury sustained on international duty.
The South American World Cup qualifier between Brazil and Argentina, which finished 3-1 to Dunga's side, has come at some cost to Mark Hughes as Tevez has picked up a knee injury that rules him out of Arsenal's visit to Eastlands.
The Argentina forward could however return in time to face his former club Manchester United for the highly-anticipated derby at Old Trafford on September 20, according to manager and fellow former Red Devil Mark Hughes.
"We heard yesterday (Monday) that Carlos had a knee problem, our doctor has spoken to the Argentine medical people and the feeling is that he is out for the weekend so he will not play against Arsenal," Hughes told the club's official website.
"The hope is that he will be okay for the derby, but we will have to determine that when he comes back. He is staying with the national squad because he needs acute treatment at the early stage of the injury, which is what he can get now. Flying him back quickly might compromise the injury, so he will be back towards the end of the week so we can assess him and hopefully get him ready for the United game.
"It was an impact injury, he has twisted his knee but it could have happened in a training session or just walking down the road. Its part and parcel of the game, we feel it's not going to compromise him too much and that it will only be one game that he has to miss."
Robinho also sustained a thigh problem in the game between the South American rivals but Hughes remains hopeful his record signing will be available to face the Gunners. The forward will play no part in his country's fixture against Chile on Wednesday.
"It's a different situation with Robi," Hughes said. "It's an old injury that he aggravated last year, just above his ankle. We are going to get him back as soon as possible, the hope is that he will be an option for the weekend but we need to get him back, which we will do today [Tuesday]."
Meanwhile, Hughes has confirmed that Kolo Toure will be Manchester City captain for the foreseeable future, including the game against his former club at the weekend. Richard Dunne previously held the responsibility prior to his move to Aston Villa.
"Kolo has taken the armband in the last couple of games, and I am very comfortable with that," Hughes said. "There might be times in the season when we might ask people to take on the mantle and show the leadership qualities that a captain has to have, but I am very comfortable with Kolo having the armband."
