Terry is desperate to play against Germany after being forced to withdraw from the squad for the double World Cup header with Kazakhstan and Belarus last month.
"I got shoved when in the air and landed awkwardly. It felt like a sharp pain in the bottom of my foot which is throbbing at the moment," he said.
"But I will have a scan tomorrow and hopefully it will give me the all clear. I am desperate to go away with England for the game with Germany. I have not been ruled out.
"I hope the scan gives me the all-clear to go away. With me having to pull out of the last squad, I am desperate to play. As England captain, I want to be there."
Blues manager Luiz Felipe Scolari could offer no more positive news on Terry's injury.
"I am not the person to give the answer regarding John Terry but the doctor said tomorrow he will go to the hospital and have a scan," said the Brazilian.
"If he is fit, he will play out of respect for the national team. If he is not fit, Capello will have a look and not play him. If he is in good condition, he needs to play."
