Germany midfielder Bastian Schweinsteiger has been given the all-clear to return to full training.
Schweinsteiger was a doubt for Euro 2012 after missing Thursday's final warm-up match against Israel due to a calf injury, but fears he may not be fit enough to play in Poland and Ukraine have been allayed by the national team's doctor Hans-Wilhelm Muller-Wohlfahrt.
"Bastian has absolutely no problems anymore," said Dr Muller-Wohlfahrt. "He has no pain. He will continue to receive treatment, but we expect him to train again with the team tomorrow. Of course he is a bit behind the others in terms of training, but I expect him to be fully available for the Portugal game."
Germany depart for their Euro 2012 base on Monday ahead of their opening group match against Portugal on June 9. Their head coach, Joachim Low, said: "There is no reason not to look forward to these European Championships.
"We are ready, we have trained well and we are pleased that things are now getting under way. We have got to focus a lot over the coming week and we have a lot of work ahead."
After facing Portugal, Germany then clash with neighbours Netherlands before finishing the group stage against Denmark on June 17.
