Ashley Cole took part in England's training session at Krakow's Hutnik Stadium as England continued their Euro 2012 preparations.
Cole missed a civic reception in Krakow on Thursday evening amid suggestions he had been suffering from a stomach bug.
But the Chelsea defender, 31, was among the first players out for an open session in front of 3,000 fans.
Jermain Defoe was the only player not on show as he has returned to England following the death of his father.
England's players were greeted very warmly by the locals and responded to the reception as they were met by a guard of honour formed by school children.
