Defender Kari Arnason and midfielder Michael O'Connor are on international duty with Iceland and Northern Ireland respectively so they will play no part in the unbeaten Millers' first league clash with the Blades since 2005.
Fit-again Claude Davis (illness) and recent signing Pablo Mills, returning for a second spell with the club, will battle it out for Arnason's spot in defence.
Mark Bradley (groin) is being monitored after suffering an injury in last week's win at Notts County, while David Worrall (muscle strain) and Mitch Rose (knee) are definitely out.
