During the regular season (when it is possible for a 'draw' to occur) the dead heat rule will apply, and your odds will be halved for that bet/leg. The dead heat rule will apply for all markets, unless otherwise stated, without the draw option.
For example:
The Saints are paying $2.20 to beat the Tigers and the match ends in a draw.
$10 stake x $2.20 odds = $22 divided by 2 = $11 return
