Colliery secretary Billy Banks said: “We have a full squad available, with Bradley Varga returning to the club from Newton Aycliffe.
“As long as the rain and snow holds off, it should be OK. They’re on a high at the minute and the top of the table is that tight between the top six or seven teams, anything can happen.”
Stockton boss Michael Dunwell has a full squad available, with Liam Jordan fit again.
Sixth-top Durham City journey to Hebburn Town, in eighth for an 11am kick-off.
Hebburn manager Scott Oliver said: “Glen Hargrave, Adam Rundle, Channon North and Chris Thompson all return, but Chris Smith will be missing.
“We were garbage last Saturday so we need a huge improvement for Boxing Day. We need to be fully focused and we’re going to improve.”
Tow Law Town travel to Willington (11am) looking to avenge August’s home derby defeat.

Town’s only doubt is Mark Dixon.
Synthonia manager Conrad Hillerby said: “It’s always a grudge match. Both teams are in a promotion position so it’s not just a local derby.
“We’re looking forward to it, and looking forward to a decent crowd.”
