Pietersen refuses to rule out Test retirement
"I can't rule out that my next Test may be my last," he said after winning the man of the match award in the drawn second Test at Headingley after a superb innings of 149, which he followed up by taking three wickets.
Pietersen's future was a major issue before the series against the Proteas began.
He has already announced his retirement from from one-day international cricket, amid speculation he wanted to be available for a full Indian Premier League programme while still playing for England and play in the upcoming World Twenty20 in September.
"That is two of many points," he said. "But they're not the main two points. Let's make that very clear, there are other points I am trying to sort out in the dressing room.
"There are a lot of other issues. It's absolutely 100% not a money issue. You'll find out soon enough, not tonight. It will be a lot clearer after the next Test match."
Pietersen said it would be a "huge shame" if his Test career came to an end.
"I love playing Test cricket for England," he told reporters. "The saddest part for me is that the spectators just love watching me play and I love playing for England but the politics is what I have to deal with personally.
"It's tough for me playing for England."
Sachin Tendulkar announced his retirement from international cricket after playing his 200th Test in the home series against the West Indies next month.
