Fabricio Coloccini won’t face Club Atlas in Milwaukee tonight.
Newcastle United’s captain missed the pre-season opener against Gateshead last week.
And Coloccini is not in the starting XI, or among the substitutes, for tonight’s game at Miller Park (2am kick-off BST).
United head coach Steve McClaren admitted the captaincy was an “issue” ahead of the game.
But McClaren insisted that the long-serving defender would skipper the side if fit.
Crystal Palace manager Alan Pardew – who managed Coloccini at Newcastle – has been linked with a move for the 33-year-old.
Midfielder Jack Colback will again captain United in Coloccini’s absence.
And goalkeeper Tim Krul will make his first appearance of pre-season.
NEWCASTLE UNITED: Krul, Janmaat, Williamson, Lascelles, Haidara, Anita, Colback, Sissoko, Gouffran, de Jong, Cisse. Subs: Darlow, Woodman, Ferguson, Bigirimana, Obertan, Aarons, Armstrong, Perez.
