A month ago England had an abundance of top right-backs, with boss Gareth Southgate spoilt for choice.
But now he may well be having to think of alternate options for next month's World Cup following a spate of injuries.
Chelsea's Reece James was the latest right-back to suffer a problem, going off midway through the second half of his side's 2-0 Champions League win at AC Milan with a leg injury.
It is the latest blow for Southgate in a position where England had looked blessed with options.
Manchester City's Kyle Walker, with 70 England caps, suffered an injury in the 6-3 derby win against Manchester United at the start of October.
