The 28-year-old has been ruled out for the remainder of the domestic season but has come off crutches and is undergoing gym work and swimming as the first part of his recovery programme.
He said: "It's too early to say for England. We'll have to wait until I'm outside running and kicking a ball.
"The quicker I'm out on the pitch running, the quicker I can have an inkling about Euro 2012.
"But I am on the mend, can walk without crutches and have just started rehab work in the pool and also doing stuff in the gym as well."
Bent had established himself as one of England's first-choice strikers since his £18million move from Sunderland 15 months ago.
