England skipper Andrew Flintoff is unsure whether he will be able to bowl in the Champions Trophy as he continues to make his comeback following ankle surgery.

"I'm not certain I'll bowl in the Champions Trophy, though I'm feeling stronger in the nets," Flintoff told reporters on Thursday.

England's inspirational all rounder is in a race against time to regain his form with bat and ball with the Ashes tour in Australia starting in November.

However, Flintoff scored 59 in a warm-up game on Thursday.

He

batted at number three, after a long batting stint at Wednesday's nets, to strengthen speculation he could open the innings during the Champions Trophy to cash in on fielding restrictions.

"I'm not sure about the batting line-up. This match does not in any way give a clue to that," he said.

"It requires a lot of strategies and the line-up will only be decided on Sunday."

The 2004 finalists open their campaign against hosts India in a group B tie in Jaipur on Sunday.
