Newcastle goalkeeper Martin Dubravka is set to be sidelined for at least a month amid fears he has broken a metatarsal.
Sources say it will be the end of August before he is likely to return, meaning he will miss the Premier League opener at home to West Ham.
Karl Darlow will deputise, as he did last season when an ankle injury kept Dubravka out until January.

The Slovakian did not win back his starting spot until March and, had Darlow not reverted to the bench, England boss Gareth Southgate admitted there was a chance he could have been handed a senior call-up.
