There will be no wild-cards competing in the Donington Park round of the World Superbike Championship, reducing grid numbers to 21 riders.
The provisional entry list had included three wild-cards, with Michael Rutter and Martin Jessopp initially set to appear with the re-branded Rapid Ducati team, while Chris Walker was down to make a surprise appearance with the newly-formed Pr1mo Kawasaki outfit.
However, with a month to go before they participate in the British Superbike season opener at Brands Hatch, both teams have decided to focus on getting prepared for that instead.
They join Samsung Crescent Suzuki in scrapping plans to race alongside its world championship counterparts, though the Jack Valentine-helmed squad says it will race in the second UK event at Silverstone later in the year.
It is the first UK-based event to feature no BSB regulars since 2007.
It means the standard 21 riders that will race full-time in 2011 will compete at Donington Park, including Chris Vermeulen, who is listed to make start his first WSBK race in eight months.
In the World Supersport class, just one British championship regular is listed, with Irishman Jack Kennedy set to line up with the Colin Appleyard/Macadam Racing Yamaha.
