Rashford missed England's first training session in Russia after picking up a knock before the team flew out for this summer's tournament, raising doubts over his involvement against Tunisia on June 18.
However, the 20-year-old has insisted that the problem is only a minor one and is confident that he will be available for the match in Volgograd.
Thanks for the messages I've been getting. Picked up a slight niggle but nothing to worry about 👊🏾 #ThreeLions— Marcus Rashford (@MarcusRashford) June 13, 2018
