Lowry, on loan from Aston Villa, has missed the last two games and although Adams has no new injury or suspension worries, he could be tempted to tinker with his line-up as he chases his first win in charge at Bramall Lane in 14 games.
Midfielder Nick Montgomery (knee), striker Sam Vokes (hamstring), on loan from Wolves, and another loanee, West Brom defender Joe Mattock (ankle/knee), all returned to the substitutes' bench on Saturday and could be included in Adams' side.
Skipper Chris Morgan, fellow defenders Andy Taylor and Ryan France, goalkeeper Richard Wright and striker Darius Henderson remain sidelined.
The Blades are second-bottom of the table, six points adrift of safety with 11 games remaining.
