England captain Michael Vaughan passed himself fit for Thursday's second Test against New Zealand after his suspect knee came through unscathed in a county match on Monday.
Yorkshire batsman Vaughan missed England's seven-wicket first Test win at Lord's after injuring his left knee in the nets.
But on Monday he played for Yorkshire in their one-day league match away to Scotland, scoring 32 off 62 balls before being run out.
Yorkshire won the match at the Grange by 59 runs and afterwards Vaughan said of his knee: "It's fine. I trained pretty hard last week and the rehab went pretty well. Plus I have come through a good game of cricket which was a good Test.
"I never say there is no trouble with my knee because I have had dodgy knees for a few years now," added Vaughan ahead of the second Test at Headingley, his home ground.
"But what happened at Lord's was just bad luck and I'm hoping it never happens again.
"I'm going into the game on Thursday one hundred percent fit."
Vaughan's place at Lord's was taken by Middlesex captain Andrew Strauss who marked his Test debut by scoring 112 and 83.

However, Vaughan told Sky Sports earlier on Monday he was ready to return to number four, where he began his Test career, and leave Strauss at the top of the order.
"There is a good chance I will go down to number four," Vaughan said.
England's regular number four, former captain Nasser Hussain, announced his retirement from all cricket following his match-winning unbeaten hundred at Lord's.
Thursday's match is the second in a three-Test series.
