Marcus Rashford missed England training on Wednesday with a slight knee strain, but the injury is not thought to be serious.
The 20-year-old underlined his claims for a starting place in England's World Cup opener against Tunisia with a man-of-the-match display and outstanding opener against Costa Rica last week.
England manager Gareth Southgate revealed upon landing in Russia on Tuesday that the Manchester United forward had sustained a "slight knock" - a knee complaint that kept him out of the first training session as a precautionary measure.
Tottenham midfielder Eric Dier trained with strapping on his groin which he later explained was simply to protect a long-standing minor injury.
"It's really nothing to worry about. It doesn't affect me at all," he told Sky Sports News. "It's more of a habit to be honest."
England face Tunisia in their opening World Cup game on Monday before they face Panama and Belgium in their remaining Group G fixtures.
