Anderson's county Lancashire has received scans that confirmed that the 23-year-old seamer suffered a stress fracture of the lower back, the ECB said.

He will be out for at least two months and will also miss the five Sri Lanka one-day internationals.

Anderson has not featured for Lancashire since returning from England's tour of India and had been considered doubtful for the Test series against Sri Lanka which starts on May 11.

England suffered another blow on Monday when fast bowler Simon Jones left the field with knee trouble during Glamorgan's C&G Trophy match against Ireland.

Jones, who missed England's tours of India and Pakistan with ankle and knee problems, was also due to have a scan on Tuesday.

England captain Michael Vaughan (knee injury), fast bowler Steve Harmison (shin) and spinner Ashley Giles (hernia) are all ruled out of the first Test at Lord's.
