England forward Marcus Rashford has suffered a "slight knock" in the final training session before heading to the World Cup in Russia, manager Gareth Southgate said.
The 20-year old, who scored 13 goals for Manchester United in all competitions last season, will be hopeful of a starting spot in Southgate's team after impressing in the warm-up games, including a long-range goal against Costa Rica.
"Marcus took a slight knock but nothing too serious so we will have a look at that ahead of tomorrow's session which is open for everyone to see," Southgate told British media.
"We have another week of preparation and a lot of competition for places, as you know."
Southgate has not yet decided on the starting lineup ahead of Monday's World Cup opener against Tunisia, saying there are "one or two very close calls" which will be decided once training resumes in Repino.
England will also face Panama and Belgium in Group G.
Iran's Queiroz slams Nike over World Cup boots
Iran coach Carlos Queiroz has called on Nike to apologise to his team after the US sportswear firm said it could not supply the players with football boots for the World Cup due to sanctions.
"US sanctions mean that, as a US company, Nike cannot supply shoes to players in the Iranian National team at this time," Nike had said in a statement.
Queiroz, whose side face Morocco in their Group B opener on Friday, said it was an unnecessary statement and asked FIFA to help.
"It has been a source of inspiration for us," Queiroz told Sky Sports. "This last comment of Nike was, in my personal view, an unnecessary statement. Everybody is aware about the sanctions.
"They should come out and apologise because this arrogant conduct against 23 boys is absolutely ridiculous and unnecessary."
