Nigel Adkins’ men travel to The Den for the third round tie as the Championship takes a break for the famous knock-out competition.
It will be the Tigers’ second trip to South East London in the space of a month having drawn 1-1 with the Lions in the league in early December.
Head Coach Adkins may look to rest some members of his squad after a hectic festive schedule, although Henriksen insists that, whoever plays, progression to the fourth round will be the Tigers’ only aim.
“Every competition is important and whoever plays, we’ll go to Millwall looking to progress to the next round because it’s important that we keep our momentum going,” he said.
“If we win again – it would be a sixth successive win and eight games unbeaten – and that is very important for us.
“It’s the Third Round of the FA Cup and changes will probably be made due to the hectic nature of our recent schedule but that doesn’t affect the team’s desire to win.
“Some new players will get the chance to impress and stake their claim. It’s a great opportunity for them to show that they want to play and be involved from the off in the league.
“To see the depth we have at the club now when everyone is injury-free is very positive. Everyone will be given a chance and hopefully, they can take it.
“I’m sure some of the younger players will want to show what they can do and what they’re capable of by being part of a team that progresses to the next round of the cup.”
