Kevin Pietersen [Images] has ruled himself out of the running to be England's [Images] one-day captain.

"At this stage of my career... I don't think it's the right time for me yet," the batsman told reporters.

"I'd be humbled in the future to be given the opportunity to captain my country but right now I don't think it's the right time for me."

England will name their new one-day captain on Friday with all-rounder Paul Collingwood [Images] now clear favourite to replace Michael Vaughan [Images].

"Whoever gets the job tomorrow gets my full support," added Pietersen.

"It's a new era now, it's a good time for English cricket to go forward."

Pietersen said the England selectors had discussed the one-day captaincy with him.
