Castletown take on Governors
Union Mills are preparing for a tough afternoon as they line-up against free-scoring Pulrose later.
The Groves Road club have netted 59 times in just 12 outings so far in JCK Limited Division Two this season.
Castletown will be looking to capitalise on any slip ups the league leaders make, though.
They'll go top if they beat struggling Governor's Athletic and Pulrose fail to win.
