Dunne has full complementManager Joe Dunne has no injury worries ahead of the trip to Bramall Lane and will be hoping the U's continue their great start to the Sky Bet League One season.
The U's travel to Sheffield United with a full squad this weekend.
An impressive performance in the victory over Port Vale could see Dunne stick with the same eleven starters but there are a number of players waiting in the wings, ready for their chance.
The likes of experienced duo Kem Izzet and Clinton Morrison will be hoping for action, along with youngsters who impressed in the midweek win over Arsenal U21s.
Drey Wright, Alex Gilbey, Daniel Pappoe and Josh Thompson all shone against the Gunners and will provide competition for places for Dunne's first team.
U's: Walker, Cousins, Wilson, Dickson, Pappoe, Eastman, Thompson, Okuonghae, Wright(David), Izzet, Bean, Bond, Eastmond, Gilbey, Wright(Drey), Watt, Massey, Sears, Morrison, Ibehre.
