"We haven't really sat down and spoken a lot about the complete make-up of the squad for the World Cup," Ponting told AAP.

"We've been waiting on a few guys as well, waiting to see how Watson comes up and those sorts of things. If he does make it into the squad, he basically plays as another fast bowler anyway. It would probably be five fast bowlers plus him."

"We've all seen in the last week that he got through the game in Brisbane pretty well, made runs and did the amount of bowling he was supposed to do. He's got a little bit of cricket under his belt but whether or not he takes part in the remainder of this series, I don't really know. I just hope that he can recover as quickly as possible and start putting some good performances on the board before the World Cup comes around."

Ponting said Watson, who was promoted to open with Adam Gilchrist throughout the Champions Trophy, would be a strong chance to play at the top of the order should he prove his fitness for the World Cup.

"I wouldn't imagine he would be in the middle order anywhere," Ponting said. "I think the middle order is pretty settled at the moment with Michael Clarke at four, Andrew Symods, Mike Hussey and those guys."
