O’Brien replaced Joe Martin in the 64th minute of the 2-0 JPT defeat to Oxford last night with Shane Ferguson dropping back to left-back. Steve Morison, Lee Gregory and O’Brien have scored 30 times between them this season and against a side with the fifth best defensive record in the division, so Harris could decide to include all three to increase our goal threat. Harris refused to say whether there will be a change in goal following David Forde’s error against Oxford when he let Kemar Roofe’s cross in at the near post, but it would be a surprise were he to drop the 36-year-old Republic of Ireland international, who has been in good form recently. Ed Upson could put pressure on Shaun Williams or Jimmy Abdou for a place in midfield, while Jed Wallace will play his second successive game at The Den following a promising display on Thursday. Defender Ryan Inniss is available again for Port Vale after injury, while veteran midfielder Michael Brown, who will turn 39 this month, could keep his place in midfield after featuring in Port Vale’s last two games. Those 1-0 wins over Bury and Blackpool leave them just a point behind Millwall in the league table.
