England winger Theo Walcott has been ruled out of Tuesday's World Cup qualifier against Ukraine at Wembley due to illness. Southampton's Adam Lallana, Tottenham's Jake Livermore and Liverpool's Raheem Sterling have been added to the squad as cover, the Football Association confirmed Monday.
Daniel Sturridge and Walcott were absent from England's final training session Monday.
The duo trained Sunday, but complained of feeling unwell overnight and did not participate in the session at Arsenal's London Colney training complex.
It left head coach Roy Hodgson with only 18 players to be put through their paces after the withdrawal Sunday of defender John Terry with an ankle problem.
Meanwhile, a weekend surge in ticket sales means 68,000 have been sold for the clash against the Ukrainians, the Football Association confirmed.
The figure includes 6,500 which have been sold to Olympic Games volunteers at the reduced price of £20.12 ($32).
At half-time, 15 Team GB medallists will be presented to the crowd.
