Burnley could seek dispensation from Uefa to register keeper Adam Legzdins for the Europa League second qualifying round second leg with Aberdeen, reports BBC Sport.
Nick Pope had shoulder surgery after suffering an injury in the 1-1 first-leg draw and Tom Heaton is a doubt.
Anders Lindegaard, who came on in the first leg for his first game since 2016, has a slight thigh injury but is fit to play.
Fourth-choice keeper Legzdins was not named in their European squad.
The 31-year-old joined the club from Birmingham last summer but has yet to play a game for the Clarets.
