The striker was shown a straight red card for an elbow on Doonhamers player Ryan McGuffie just 11 minutes after he had come on as a substitute.
That meant he would automatically miss this Sunday’s home Third Division meeting with Montrose through suspension.
But the SFA has applied a two-match ban after receiving referee Stevie O'Reilly's report and that also sees him sit out the visit of the Steelmen six days from now.
Manager Ally McCoist is already short of attacking options as it is with Andy Little and David Templeton both currently out with injuries.
Losing Kyle for two games rather than one is a further setback and it leaves only captain Lee McCulloch, Fran Sandaza and Kal Naismith as recognised strikers in his squad.
In turn, that could see youngsters such as Callum Gallagher and Jamie Burrows come into contention for promotion from Tommy Wilson’s reserve squad.
Gallagher in particular has begun the season well, scoring in both of the second string’s league wins against Annan and East Fife whilst netting regularly for the under-20 side.
