Security will be tightened around Werder Bremen's home Bundesliga clash against second-placed VfL Wolfsburg on Sunday after police warned of a possible terrorist attack in the Hanseatic City.
Local police have stepped up their presence in Bremen's central areas due to a warning of possible Islamic terrorist activity in the city, from Federal police, on Friday night.
"The Bremen police department has increased its presence in the city and stepped up protective measures in public areas," said a Bremen police spokesman.
Werder has said the league match will not be postponed, but the club are in constant contact with the police's operations centre.
Security measures will be increased around the club's 42,100-capacity Weserstadion ground before and during the match.
"At the moment, there are no thoughts of postponing," Werder's general manager Thomas Eichin told magazine Kicker.
"But we will monitor the situation constantly."
The match is one of the league's top clashes this weekend with Bremen unbeaten in their last six outings which has taken them from last to eighth.
Other sports fixtures in the region could be affected on Sunday with Bremerhaven meeting Oldenburg in a Bundesliga basketball match, with a crowd of 9,000 expected.
