Doyle and Burgess to start at Grimsby
Christian Burgess and Michael Doyle will keep their places in Pompey's side for the trip to Grimsby.
Paul Cook has indicated he will name an unchanged line-up, meaning the duo who came to blows in the Blues’ dressing room against Stevenage will feature. That ensures the visitors will be at full-strength against the Mariners.
Elsewhere, Jack Whatmough is still troubled by the slight hamstring problem which kept him out of the under-23s’ trip to Everton on Monday.
And Curtis Main remains sidelined with an abdominal strain.
