Boston Town head off to Desborough loking for revenge.
The Poachers lost 2-1 against Ar Tarn in early October.
But the shape of the game was changed when defender Michael Wood was sent off early on, for what seemed an innocuous challenge.
Ar Tarn made the most of the man advantage to take the three points.
But the POachers want to put that right on Saturday.
“If the match had finished 11 v 11 then we’d have won it,” said boss Ian Dunn.
“It was anothing challenge really.
“Both players went in for the ball, it was a 50-50 challenge.
“But the only difference was that Woody got up and their man didn’t straight away.”
Kick off in the UCL Premier clash at Waterworks Field is at 3pm.
