The Porsche European Tour has amended the dates and reduced to only a 54-hole event due to coronavirus travel restrictions between the UK and Germany.
The tournament, due to be held from June 3-6 at Green Eagle Golf Courses in Hamburg, has been pushed back 48 hours and shortened by a day, with the event now being played from Saturday June 5 to Monday June 7.
The decision was made after the German government placed the United Kingdom on its 'red list' for travelling.
Almost a third of the 156-player field, along with a number of caddies, European Tour staff and broadcast crew would have been impacted by the change, with the new move now enabling the tournament to still go ahead.
Keith Pelley, European Tour chief executive, said: "The significant travel changes announced last week meant it was simply impossible for us to start the Porsche European Open as intended a week today without unacceptably damaging the field and the integrity of the tournament.
"Over the past year we have had to react to numerous changes at short notice and our ability to do this has unquestionably been down to the flexibility of our players, caddies, staff, broadcaster partners and sponsors. This is another wonderful example of everybody working together pragmatically to find a solution.
"That has enabled us to not only provide vital playing opportunities for as many of our members as possible, but also to showcase this prestigious event, and Germany, properly to our global television audience."
