The controversial 32-year-old batting star spent the past month commentating on the ICC World T20 tournament in Sri Lanka, but now it is time for him to get out in the middle again and do what he does best.
Delhi start the group stages at Centurion against the Kolkata Knight Riders, but how long Pietersen is with them could depend on the reintegration process he has agreed to prior to an England comeback.
In what he has called "a horrible situation for all involved", Pietersen has not been part of the international set-up since it was revealed he had sent text messages to South Africa players during the summer series.
Last week the England and Wales Cricket Board released a statement saying Pietersen would undertake a programme of reintegration after which selectors "will consider Kevin for future matches".
He in turn stated: "I'd just like to take this opportunity to apologise to my team-mates and all the England supporters. Thankfully we have drawn a line under it and it's time to move forward.
"Playing cricket for England is the pinnacle of any cricketer's career and I want an opportunity to do that again as soon as possible. Some of my proudest and best moments of my life have been in an England shirt, and I want them to continue for as long as possible.
"I'm entirely committed to completing the reintegration process we have agreed over the coming weeks and resuming my England career in all formats, hopefully until the World Cup in 2015, as long as my body allows."
England, now with Alastair Cook as Test captain in place of the retired Andrew Strauss, fly out in less than a fortnight for a tour of India. While Pietersen is not expected back for the four Tests and two Twenty20 games before Christmas, the five-match one-day series at the start of January is seen as a possibility.
James Anderson believes England need Pietersen to help them reclaim top spot in the Test rankings and would relish lining up alongside the free-scoring batsman in the first Test against India in Ahmedabad next month. "If he is there then brilliant," the fast bowler told BBC Radio 5 live. "We want to get back to number one and we need our best players to do that - Kevin is one of our best."
