FIELD umpire Curtis Deboy will oversee the first final of his career in Saturday night's elimination final between Port Adelaide and West Coast at Adelaide Oval.

In his third season, Deboy has officiated in 54 games in his career (23 this year) after umpiring the 2012, 2013 and 2014 SANFL Grand Finals.

Deboy has been booked to make his finals debut alongside experienced umpires Chris Donlon (267 matches) and Justin Schmitt (350) in the Power-Eagles contest.

The AFL's second-most capped umpire Brett Rosebury will take charge in Thursday night's qualifying final between Adelaide and Greater Western Sydney at Adelaide Oval.

Rosebury, who will officiate in his 38th AFL final on Thursday night, will be joined by Jeff Dalgleish (164 matches) and Shaun Ryan (281).

Two of the AFL's most experienced umpires, Shane McInerney and Matt Stevic, have been locked in to officiate Friday night's marquee clash, with Geelong pitting itself against Richmond in a mammoth qualifying finals battle.

McInerney, who has officiated in 465 games, and Stevic (328) will be assisted by Matthew Nicholls, who notched his 300th career match in round 18.

Well-known umpire Ray Chamberlain will be in charge for the Sydney-Essendon elimination final duel at the SCG on Saturday night.

Chamberlain, a colourful figure in the umpiring ranks, will have Brendan Hosking (108 matches) and Simon Meredith, who received AFL life membership after joining the '300 club' earlier this year, for company in Sydney.

The umpires will be decked out in their normal green uniforms across this weekend.
