MADS Korneliussen and Manuel Hauzinger have been ruled out of Thursday's meeting against Wolverhampton because of injury.
It was hoped Korneliussen would be able to take his place in Thursday's starting line up but the Dane is still suffering the effects of his horrifying fall at Peterborough on Monday .
Manuel Hauzinger has not yet recovered from a crash in Hungary fourteen days ago.
Swindon will operate the rider replacement facility for Korneliussen with Richard Sweetman replaces Manuel Hauzinger.
Wolverhampton will be without Niel Kristian Iversen who is currently sidelined with a shoulder injury.
