MADS Korneliussen and Manuel Hauzinger have both been ruled out of tomorrow's Elite League fixture with Wolverhampton Wolves at Blunsdon.
Korneliussen will also miss Friday night's visit to reigning champions Coventry Bees after failing to recover from a hand injury he sustained in a crash at Peterborough on Monday.
He will be replaced in the Robins line-up by Richard Sweetman tomorrow, while Joel Parsons will ride for Swindon on Friday.
Hauzinger was expected to be fit to face Wolverhampton, but his recovery from the head injury he received riding in Hungary is also taking longer than expected.
