Winger Drury was a deadline-day signing from non-league outfit Luton and travelled with his team-mates for the 2-1 win at Derby on Tuesday night.
However, a hold-up in the paperwork at Luton prevented him from signing in time to play so he will come into contention against the Blades.
Jimmy Bullard marked his debut with a goal at Pride Park and should continue alongside David Norris and Grant Leadbitter in midfield.
Goalkeeper Brian Murphy is set to be out for at least three months with an ankle injury and winger Shane O'Connor remains sidelined with a dislocated shoulder.
