An extract from the rule:
Results of blood samples consistently reveal elevated TCO2 levels, however they fall
just below the threshold and therefore no action can be taken. This indicates that
trainers are administering alkalinising agents on raceday.

Very disappointing to think that Matty Craven is pushing the rules after his raw emotion after the win last week
