Two sides battling to dislodge Saturday League Division One leaders West Pier clash at Sands Lane this weekend.
Third-placed Edgehill will take on Hunmanby United, knowing that only a win will do if either side are to maintain the pressure on Pier, who have won all 12 league games so far this season.
Pier also have a tricky fixture as they play host to Filey Town, while Whitby Fishermen's Society can edge away from the relegation zone if they can pull off a shock win at second-placed Newlands Park.
