Must-win game for H&B
Chichester comprehensively beat the William Parker team 50-15 in their last encounter, but assistant coach Rob Hamilton believes his side can turn things around.
"This is a must win game for us if we want to gain promotion but even if we win our last five games we would need someone to do us a favour against Heathfield."
H&B should have a full strength squad but it will be Ben Campbell's last game for the club for a year before he jets off to play in Australia.
The game kicks-off at 2.30pm at William Parker.
