Kaiserslautern's World Cup stadium is ready to host matches again two days after a crack in the east stand resulted in its closure.
The Fritz-Walter-Stadion is the venue for five matches in the finals
The club said temporary struts had been added, after the match against Eintracht Frankfurt was cancelled.
"It's remarkable how quickly the supports were put in place over the weekend," the mayor of the city said on the club's website.
An independent building study of the stadium is due to begin this week.
The Fritz-Walter-Stadion's 40,000-capacity will be reduced to 36,000 for World Cup matches.
There have also been problems at other grounds which are being used for next year's finals.
The roof of Eintracht Frankfurt's Waldstadion failed to keep out the rain in this year's Confederations Cup final while cracks also appeared in the concrete at Nuremberg's Frankenstadion during a German Cup match.
