England spearhead James Anderson missed the whole of Saturday's play in Lancashire's Roses clash with Yorkshire because of a groin injury and may take no further part in the match.
Anderson, England's all-time leading wicket-taker in Tests, has not been in action at Old Trafford since limping off clutching his groin on Friday's first day.
The 34-year-old fast bowler had been scheduled to play in Lancashire's next four Championship matches.
However, as he is no longer involved in international white-ball cricket, Anderson does have time to recover before his anticipated involvement in England's first Test of their home season against South Africa at Lord's on July.
