I'm not ready for tests, says England one-day player Jos Buttler
England wicketkeeper acknowledges his limits after his record century against Sri Lanka

Jos Buttler believes he will eventually be able to transfer his stunning one-day form into the test arena, but now is not the time for him to make a debut in the five-day format.
The 23-year-old wicketkeeper-batsman, who joined Lancashire from Somerset at the start of this season, played one of the greatest limited overs innings yet by an England batsman, albeit in a losing cause, against Sri Lanka at Lord's on Saturday.
Coming in with England in dire straits at 111 for five in pursuit of a target of 301, Buttler made 121 with his hundred coming off just 61 balls - the quickest by an England player in an ODI match and the fastest by any batsman in England.
I haven't discussed it with the management or Alastair," Buttler said. "[But] I am not ready for test-match cricket
Unfortunately, for England, Buttler was out in the final over as Sri Lanka won by seven runs to square the series at 2-2 ahead of today's finale at Edgbaston.
England are due to name their squad for this month's first test against Sri Lanka on Thursday, with their apparent plan to recall Matt Prior after he was dropped during the 5-0 Ashes thrashing in Australia set to be scuppered by the Sussex wicketkeeper's Achilles injury.

While Buttler certainly has not done his chances of making a test debut any harm, doubts remain over the quality of his glove work and there have even been suggestions England could recall James Foster, reckoned to be the best keeper on the county circuit, 12 years after the Essex stalwart played his last test.
