Stephen McLaughlin remains on sidelines for Southend
Southend are again set to be without winger Stephen McLaughlin because of an ankle injury for the visit of Sky Bet League One leaders Sheffield United.
Forward Zavon Hines could be in contention for a first home appearance after coming off the bench in the goalless draw at Swindon following his free-agent transfer before Christmas.
Goalkeeper Mark Oxley continues his recovery from an elbow problem, while Dave Mooney and Ben Coker (both ankle) remain on the sidelines alongside on-loan Crystal Palace defender Ryan Inniss, who is out after needing shoulder surgery.
Left-back Ben Coker, out since mid-November with an ankle injury, is set to resume full training next week but midfielder Adam King has returned to parent club Swansea following his loan spell.
Sheffield United's new signing Samir Carruthers is expected to be included in Chris Wilder's squad.
Midfielder Carruthers, signed for an undisclosed fee from MK Dons earlier this week, could make his debut.
Wilder is hoping to extend Ethan Ebanks-Landell's loan spell from Wolves until the end of the season and turn Daniel Lafferty's loan from Burnley into a permanent move in time for them to feature.
Striker Leon Clarke (ankle) will be assessed but is expected to return to contention as the Blades bid for a sixth straight league win.
