Theo Walcott has reportedly pulled out of an England training session because of a hamstring complaint.
The Arsenal winger begun the session with the other 23 members of the squad at England's training base just outside Krakow earlier today.
However, the 23-year-old was soon forced to leave the field early following advice from the medical team.
Despite his withdrawal, it is believed that his decision to withdraw was a precautionary measure.
Walcott initially picked up the problem during Friday's 3-2 win over Sweden in Kiev.
