Redknapp, who is on trial for tax evasion, which he denies, has been in court and has missed training since Monday but will still be at the match on Friday evening, his assistant manager Kevin Bond said on Thursday.
Bond told reporters at the club's training ground at Chigwell, north of London, that Redknapp's absence is having "very little" effect on preparations for the match.
"Yes, he will be at the match and yes, he will pick the team," Bond said on Thursday.
"The fact that the manager has not been here has had very little impact. Harry will have a look at who's fresh and who's available - we've got one or two knocks."
"Its a similar scenario to when Harry had a small medical procedure. We didn't have him for a week or so leading up to the Fulham game," Bond said.
"The training carries on as normal, so there's not a lot of difference except that Harry's not here in the day."
"We haven't had a chance to discuss the team in great depth. There's also a game four days after the match against Wigan at home that we have to consider."
