A scan has revealed no serious damage after Tevez was taken off with an ankle injury after a heavy tackle from Birmingham captain Liam Ridgewell.
But he is a doubt for Saturday's FA Cup tie at Aston Villa and added: "The medical tests have confirmed no damage in the ankle. It is only a knock and I need two days of rest. Because of this I think there are doubts over the FA Cup match but I will have to see.
"English football is physically very hard. In this aspect it is similar to Argentina but perhaps the referees need to be more severe with their actions. In my view I take too many heavy tackles in the Premier League.
"I played with the pain after the first kick I got against Birmingham but it was damaged and when I got hit there again it was impossible to carry on.
"But the papers have praised the goal and it really was spectacular in every detail.
"The first movement and the assist from Cristiano with his heel was fantastic. He is a master and a large percentage of that goal should be dedicated to him."
