Lowry, on loan from Aston Villa, was banned for last week's home defeat to Derby after his recent dismissal at Scunthorpe, but the Australian has been awarded an extra game on the sidelines for striking out at the dug out after he had left the pitch.
Manager Micky Adams could include midfielder Nick Montgomery (knee), on-loan West Brom defender Joe Mattock (ankle/knee) and striker Sam Vokes, who has been restricted to two appearances since arriving on loan from Wolves in mid-February due to a hamstring injury.
Club skipper Chris Morgan, fellow defenders Andy Taylor and Ryan France, goalkeeper Richard Wright, as well as striker Darius Henderson remain long-term absentees.
Adams is chasing his first win in 13 games since taking charge at Bramall Lane, while the Blades have not won any of their last 14 matches.
