Lewis Dobbin faces a spell on the sidelines but does not require surgery after suffering an ankle injury.
The youngster damaged ligaments in a freak accident in training at Finch Farm just before the international break.
There was an initial fear he might require an operation, but further assessment revealed the issue was not that serious.
The 21-year-old will miss games through his recovery, however, with Sean Dyche explaining work to establish a timeframe for his return is ongoing.
Dobbin was part of the first team squad that travelled to southern Portugal with Everton in the first week of the club’s extended break following the defeat at Manchester United.
