Ashley Cole pulled out of England training early on Wednesday ahead of England's Euro 2012 game against Sweden.
The Chelsea defender stalked off, accompanied by physio Gary Lewin, during the session at Hutnik Krakow.
Cole is managing an ankle injury, and his withdrawal is thought to be precautionary. Though Cole was clearly unhappy, his movement did not seem to be seriously inhibited.
If Cole has aggravated the injury, Leighton Baines would replace him at left-back for the Sweden game.
Ashley Young, Alex Oxlade-Chamberlain,James Milner and Joleon Lescott also left training early.
Martin Kelly was the only absentee from England's training session due to a lingering virus.
