The 22-year-old Arsenal midfielder has enjoyed a superb start to the season and, with regular captain Ashley Williams ruled out by an ankle injury, Ramsey will be handed the armband for the second game in succession.
Coleman said: "It was not a difficult decision to make with the way he has been playing this season.
"He has got a knock, he came off for Arsenal at the weekend with a dead leg and we have been managing that.
"He will not train today but we expect him to be available for Friday night."
