England striker Callum Wilson is a doubt for Newcastle’s visit of Chelsea on Saturday after training separately because of illness this week.
The 30-year-old was taken off at half-time during Sunday’s 4-1 win at Southampton and has since worked away from his team-mates.
Wilson was named in Gareth Southgate’s World Cup squad on Thursday after scoring six goals from 10 appearances for the third-placed Magpies this season.
But, given his injury record, news of his sickness will no doubt be of concern to the England boss.
