Edgbaston: England fast bowler James Anderson is a doubt for the first Test against Pakistan next month after injuring his right shoulder.
The 33-year-old, the world's number one ranked Test bowler, is set to miss Lancashire's next two County Championship games.
England begin their four-match series against Pakistan at Lord's on 14 July.
Anderson suffered a stress fracture in the right shoulder blade during the third Test against Sri Lanka.
Paceman Anderson played a key role in the recent Test series against Sri Lanka, which the hosts won 2-0.
England's leading wicket-taker in Tests took 21 wickets across the three matches, including 10 as the hosts won the opener at Headingley by an innings and 88 runs.
He replaced team-mate Stuart Broad at the top of the International Cricket Council bowling rankings after taking 8-94 in the second match of the series.
