Ashbrooke Belford House, in sixth position, have lost captain Lewis Hutchinson for the rest of the season.
The influential Hutchinson has suffered a knee injury, wrecking his hopes of leading Belford to their best ever league finish (sixth place in 2012/13) since joining in 2007.
Tomorrow, Ashbrooke entertain Spennymoor Town Reserves at Silksworth (2pm) and once again joint manager Asa Dobbing is forced to ring the changes.
As well as missing Hutchinson, Stephen Halliday, Kevin Humble and Adam Hopps are suspended. Fortunately, Michael Young and Lee Andrews are available.
Spennymoor boss Carl Beasley names his strongest pool of players, which includes Chris Foster, now that he has recovered full fitness.
Fifth-placed Sunderland West End, with games in hand on the four sides above them, will aim to maintain their promotion challenge by winning at third-bottom Prudhoe Town.
Manager Anth Nelson has a clean bill of health. David Keithley is likely to partner Barry Turton up front, with Jamie Fryatt, Lee Smith and John Cook forming the midfield.
Brothers Jack and Thomas Wanless and Ryan Chambers are named by Prudhoe, who have Rob Grainey serving a ban.
Horden CW have only played twice since October and manager Martin Mulcaster is desperate for the fixture at bottom club Murton to go ahead.
In view of the lengthy period of inactivity, it’s no surprise that he is able to announce a full squad.
Regardless of results, Redcar Athletic will go into the Christmas break in pole position, but they are looking to at least maintain the five-point lead they enjoy over Stockton Town.
The Seasiders are at Boldon CA and there’s a good chance that midfield pair Lance Skelton and Kristian Kamara will make the line-up.
Boldon are looking to do the double after securing a 2-1 victory at Redcar in August. Manager Paul Mossa is keeping his fingers crossed that Adam Sharp, who scored one of the two goals in the earlier fixture, will be able to play after being sidelined for six weeks with a calf injury.
The news is not so good regarding Michael Pickering, however, and a shoulder injury will again keep him on the sidelines.
Stockton Town, who have conceded only five points out of a possible 48, have five games in hand on Redcar before hosting Jarrow.
Tom Coulthard, Tony Johnson, Michael Arthur and Sonny Coleman all miss out, but James Crossman could make his first appearance of the season for Stockton.
Jarrow will be near to full-strength, their only absentee being Brodie Simpson.
Third-placed Cleator Moor Celtic are without a fixture and Hartlepool will leap-frog them if they see off visitors Richmond Town.
Pool have re-signed Luke Naylor from Horden CW and he goes straight into the squad with returning trio Ash Clark, Ash Turnbull and Matty Gardner.
Callum Hudson is still struggling with a shoulder injury and youngster Mitch Rookes is likely to replace him in goal.
Richmond also have three players back in the frame, with Mark Edzes, Lee White and Kalumn Holbrook available again.
There’s a chance that Connor Lyon will be able to play after being out for a number of weeks, but definitely missing is Michael Gunnell.
