The 38-year-old former Wales international head-butted Caerphilly prop Geraint Liddon at a ruck in the first half at the Millennium Stadium. The tight-head was forced to leave the field for stitches after the offence.
Referee Nigel Whitehouse did not see the attack, but the Cheesemen cited Jones after it was picked up by BBC Sport Wales cameras.
Neath claimed an easy 13-36 triumph in the game, running in five tries.
