You need a variable which is tapped into the System.DateTime.Now() and then you would use this variable in your query:
Code:
<CFQUERY NAME="SHOWTEAMFIXTURES" DATASOURCE="x">
SELECT * FROM ontheball_fixtures
WHERE HometeamID =#ID#
OR AwayteamID=#ID#
AND Date > #Variable#
ORDER BY Date DESC
</cfquery>
