James Milner sat out training with the England squad on Tuesday as Gareth Barry played a full part in the session.
Aston Villa midfielder Milner, who played the second half of Monday's warm-up win over the Platinum Stars, did not join in with his team-mates at the squad's Bafokeng Sports Centre base.
He reported a slight temperature and was confined to the hotel as Fabio Capello continues to work on his starting line-up for Saturday's World Cup opener against the United States.
Milner's former Villa colleague Barry was back in full training on Tuesday, although he will not be available for the game against the USA.
Barry has not played since suffering an ankle injury during Manchester City's UEFA Champions League showdown with Tottenham Hotspur in early May.
The midfielder had been given a deadline of Sunday 13th June to return to full training, but is ahead of schedule in his recovery.
The 29-year-old was one of only two players not to feature against the Platinum Stars, with David James also missing as he rested a minor knee complaint.
Chelsea duo Ashley Cole and Joe Cole spent the morning in the gym, the former as a matter of course the day after a game, the latter as the only England player to complete the full 90 minutes against the Platinum Stars.
They were joined by Ledley King, who does most of his training in the gym, while Shaun Wright-Phillips took it easy after picking up a knock to his knee.
The remainder completed a light session, including James, who played no part on Monday and seems highly unlikely to figure against the United States.
