CHINNOR coaches Matt Goode and Andrew Smith were both shown yellow cards as their side went down 38-0 away to lowly Dings Crusaders.
It was one to forget for Chinnor, who trailed 28-0 at the break after tries from James Holcombe (2) and Sam Cox.
Mark Woodrow made light of tough kicking conditions to land two conversions and three penalties.
Chinnor centre Goode was sin-binned by referee Mike Hudson before the break and Smith followed him later.
Bristol-based Dings did not have it all their own way in the second half and were restricted to two further tries from Joe Dancer and James Oakley.
