Centre-back Chris Richards sat out the USA's final pre-tournament friendly with ankle ligament damage sustained at Crystal Palace on 17 May; he trained on Friday 5 June but was not fit to play 1. "I got a little annoyed and I am not happy, because Chris Richards is an important player," Mauricio Pochettino said 2.
The timing turns a medical question into a roster one. FIFA rules let a nation replace an injured squad player until the day before its first group match, which sets Pochettino's deadline at Thursday 11 June 3. He can hold a defender who may not be fit, keeping the experience but risking a usable place going to waste, or swap him for cover and concede that experience for good. With the 4-3-3 settled at the Senegal match and confirmed against Germany , there is no further friendly to test the answer.
Richards is one of the few US centre-backs with regular Premier League minutes, which is what makes the call awkward rather than routine. A fully fit squad treats the replacement window as a formality. A defence already short on depth treats it as a gamble either way, and Pochettino has framed it as exactly that.
