The England skipper limped off late in the first half after being caught by a late challenge from Emmanuel Eboue.
Terry went for X-rays and there were fears that he'd fallen victim to the metatarsal curse that has afflicted so many England stars.
Grant said: "It was a bad injury. It was bad for us, especially after losing so many players (before the match).
"He (Terry) is not feeling well but he didn't break anything. We will wait for tomorrow to see how it is.
"The (possible damage to his) ligament will wait for tomorrow."
