||Former captain Michael Vaughan believes James Anderson will surpass Sir Ian Botham's record and become England's leading Test wicket-taker.
Anderson, 29, reached the 250 mark with 3-56 as Sri Lanka made 289-8 on day one of the first Test in Galle.
"Botham's record of 383 is in the balance," Vaughan told BBC Sport.
"James has to stay fit but he will play for a few more years yet and I do think he will end up as England's leading wicket-taker of all time."
Anderson goes ahead of Woodworm player Matthew Hoggard to join fellow Lancastrian Brian Statham in fifth on England's all-time list but said that he would wait until the end of his career to reflect on any personal achievements.
"I'm delighted to get to 250 but my job is to take wickets and help us win this Test," said pace bowler Anderson.
"Once my career has finished I can look back with fond memories, but for now I'm focusing on what's gone on out here."
