ANDREW Brayshaw and Jack Martin have had their fines for careless contact with an umpire upheld after both challenged their $1500 sanctions with a written submission to the Tribunal.

The Fremantle midfielder and boom Carlton recruit were the first players to contest Match Review fines via a letter to the Tribunal.

Under new streamlined Tribunal rules introduced last December, players challenging financial sanctions can now do so via written submissions that will be assessed by a single legally-trained jury member.

As a result, neither player will be made to attend a specific hearing to challenge a financial sanction, with the decision to be relayed via the AFL on behalf of the Tribunal.

Players electing to challenge charges that involve suspensions in the future will still have to attend an AFL Tribunal hearing to present their cases, as per previous years.

Brayshaw and Martin were two of six players charged by the Match Review from Saturday night's clash in Mandurah, with Sam Docherty, Jack Newnes and Blake Acres all accepting $1000 penalties for engaging in a melee during the second quarter.

David Cuningham was also handed a $1500 fine as a fixed financial sanction for striking.

Elsewhere, Sydney's James Rowbottom was fined $1000 for making careless contact with an umpire – however, the Swans youngster has chosen to accept the ruling.

Collingwood midfielder Taylor Adams has also accepted a $2000 sanction for rough conduct, following a strong bump on Richmond premiership defender Nick Vlastuin.
