Lawes, who captained England in all three summer tests against Australia, took a blow to the head during Northampton's defeat to Leicester Tigers in the Premiership on September 24th in his only appearance of the season so far.

Lawes missed the first two rounds of this year's Six Nations due to a concussion suffered on club duty in January.

World Rugby changed its Graduated Return to Play (GRTP) protocols from July 1 which now require that elite players with concussion symptoms avoid playing for at least 12 days.

London Irish flanker Tom Pearson has been called up as cover and will meet up with the 36-man squad on Monday for the five-day camp.

England face Argentina on November 6th and Japan on November 12th before two heavyweight clashes against New Zealand and South Africa on consecutive Saturdays after that.
