There has been speculation in the media on Friday that Lennie could bring back Barker, Croft and Bonner as well as Earnshaw but that appears to be a standard story on the newswires.
Lennie will ditch the 4 - 5 - 1 played at Vicarage Rd last week and revert to a 4 - 4 - 2 with no left wing but three central midfielders.
Likely team then
Margetson, Weston, Gabbidon, Prior Vidmar, Langley, Boland, Kavanagh, Whalley, Earnshaw, Thorre.
Subs, Alexander, Lee, Campbell and two from Croft, Barker and Bonner.
Sheffield Utd have revealed that new signing Dean Sturridge will start the game. The hugely experienced striker has joined the Blades on loan from Wolves and has permission to play in the FA Cup.
