Heath travel to the east coast to play Scarborough in Yorkshire One, hoping to perform better than in previous seasons when this fixture has come towards the end of the campaign and resulted in lacklustre performances.
The hosts have run into form with three wins out of their last four games and they have three points more than Heath from one game more.
The North Dean men have slipped down the table in the second half of the season, drawing 10-10 at Huddersfield YMCA in their latest match a fortnight since.
Heath won the first meeting 14-10 on December 3 but are again hit by injuries and absentees.
Ben Mitchell, who like prop James Watson has picked up a shoulder injury, is missing so Karl Craven moves forward to cover the centre berth and Cameron Ramsden makes a welcome return on the wing. Richard Cole is back at scrum half and Si Brown plays in the centre.
In the forwards, livewire Olly Wilby is unavailable so Olly Collinge comes into the back row alongside Dave Montgomery and Jeff Jones. Olly Cook starts at prop, so the second row partnership is Ian Downsborough and Ryan Hunter.
On the bench, flyer Josh Lister covers the backs and Joe Cox and Jim McCready do the same for the forwards.
Given good conditions and a decent playing surface, Heath are optimistic of a good showing. Supply of ball will be pivotal and, whilst the scrum should pose no problems, lineout possession will need to be secure.
Heath have no second team game but the thirds travel to Bradford and Bingley in confident mood after last week’s win over Halifax Dukes, a victory that confirmed then as second in their merit league.
