The Tigers travel to The Den for what will be their fifth game in 16 days and Adkins will use the third round tie as an opportunity to utilise his full squad as they go in search of a sixth successive win.
Fraizer Campbell is unlikely to be risked after missing the last two games with a hamstring injury, although positive news on the injury front is provided by Ondrej Mazuch’s return to training.
Despite plans to freshen up the side, Adkins insists the objective to win the tie and progress to the next round of the competition remains the same.
“We’ll make changes for the weekend,” Adkins said at his pre-match press conference at the University of Hull Training Ground.
“I’m very respectful of the FA Cup but I think a lot of teams will do the same this weekend due to the number of games there has been over the Festive period.
“Sunday’s gives us an opportunity for one or two players coming back from injury to feature whilst also presenting an opportunity for some of our youngsters to play.
“George Long will start from a goalkeeping point of view – I’ll put that out there now – because he’s an excellent goalkeeper and gives him a great opportunity to go out and play.
“Keane Lewis-Potter will travel and be involved in the squad. I’ll probably be looking to involve him from the bench.
“David Milinković will have an opportunity also. I’ve utilised the whole squad over Christmas except for David.
“It’s an opportunity for players who are in and out of the team. It will be a very competitive game, but it’s about utilising the whole squad – and that has been demonstrated by the good run we’re currently on.
“I’ll assess where we are with everybody after training today (Friday) and I’ll decide what I’m what going to do selection-wise after that tomorrow to go into Sunday’s game.
“Millwall are in good form having won their last three games and it was a tough, tough game at their place last month in the league.
“I have to think about the number of games we’ve played of late though and we have to give ourselves the right opportunity to be ready for the next game in the league against Sheffield Wednesday.
“I know we’ll have supporters going down to Millwall to support the team and our objective will be to go there and win – like every other game we play.”
Reflecting more on 17-year-old Lewis-Potter’s involvement in the squad, Adkins added: “He’s a young player who I don’t want to have any expectations or pressure on him. He’s a young lad who’s going to find his way with us over the next couple of years.
“It’s great that he’s scored some goals in the under-23s but it’s a totally different kettle of fish playing in the Championship.
“He’s a young guy, diminutive in his figure, he’s got a bit of pace and an eye for goal. He’s trained with the first team and he’s found that tough but it’s all part of his development as he comes through.
“Let’s not put any pressure on him but let’s be excited that somewhere down the line it’s another player coming through the academy who’s got a bright future at the club.
“Anything we get from him now is a bonus. But it’s all part of his development.”
