James Anderson may well have taken his maiden ODI five-wicket haul with the added handicap of a broken toe - to go with his dodgy knee.

Anderson revealed after his five for 23 had helped England into a 2-1 lead against South Africa at St George's that he needed treatment for the stubbed toe on his left foot.

But England coach Andy Flower explained the toe - next up from his big one - was probably troubling Anderson more than the niggle in his right knee, which is gradually clearing up.

Either way, the fast bowler's participation in Friday's final match of the series is not in doubt.

Asked about Anderson's knee problem, Flower said: "He might also have a broken toe.

"He stubbed a toe in the team room the other day, and it's either horribly bruised or broken.

"But he'll be fine. The doctor's had a look at it and he's not even going to x-ray it - because he says 'Look, if it's got a crack in it there's nothing much we can do anyway'."

Anderson had already sheepishly explained last night how he hurt his toe.

And Flower confirmed: "I think he just clumsily careered into a chair.

"He had to have some sort of anaesthetic on it before he played - so he did very well.

"But his knee is improving a lot - and he looks to be getting closer to full fitness."
