England striker Wayne Rooney was out on the training field on Thursday despite picking up an ankle knock against Slovenia.
The Manchester United ace was substituted after 72 minutes of the vital 1-0 win on Wednesday as Fabio Capello's side qualified from Group C.
He appeared to go over on his ankle moments earlier, causing him to hobble around the pitch before he was removed.
The sight of Rooney limping caused concern within the England camp, as a similar problem kept him sidelined for a prolonged period towards the end of the 2009/10 campaign.
England medical staff were, however, quick to play the problem down, insisting the injury was nothing more than a minor complaint.
The sight of Rooney heading out for training with his team-mates at England's Rustenburg base on Thursday appears to support that prognosis.
He did head off for a gym session early on, while the majority of the squad were put through their paces out on the training pitches, but he was moving freely.
Capello announced immediately after the game against Slovenia, which saw England book their place in the last 16, that he expected Rooney to be fit to face Germany on Sunday and he will be delighted to see his star striker back in action.
Of greater concern to the Italian at present are ankle problems sustained by Aaron Lennon and Michael Carrick.
Both men were forced to sit out training on Thursday, putting their involvement at the weekend in doubt.
Tottenham winger Lennon started England's first two games in South Africa, but was left out against Slovenia as James Milner took over on the right.
Manchester United midfielder Carrick is yet to see any action, having been benched throughout the group stage.
Ledley King is another of those facing a race against time if he is to face the Germans, with the centre-half still nursing a groin strain.
He was able to take part in a light session on Thursday, as he trained away from the rest of the group, but the England staff are reluctant to push him too hard.
