AFL umpire Ray Chamberlain has voiced his concerns over the potential introduction of a send-off rule.

The send-off rule was called for last-season following the Andrew Gaff incident which left Fremantle player Andrew Brayshaw sidelined for the rest of the season with a broken jaw after being struck by the West Coast midfielder.

Chamberlain said the send-off rule is decision he would not be willing to take as an umpire.

"I think anybody with an open mind and clear lens would say at different levels, there are directly different requirements," Chamberlain told SEN Mornings. 

"If the player can't keep on playing, then we're one short for that side that was offended against."

"That's probably the one thing that's of most interest to me."

"I don't think we see the prevalence of these incidents that would warrant a shift where sending a player off will be appropriate.

"Things happen really quickly on a football field and as an umpire, I've made some horrible blues, so you wouldn't want to get that one wrong."
