Richmond coach Damien Hardwick has had a cheeky dig at the umpires, following Saturday night's loss to the Giants.

The Tigers went down by two points in a frantic contest, although Hardwick had to mention the umpires post-match, after a couple of controversial calls during the second quarter.

One surrounded returning Giants forward Toby Greene, who seemed to duck into a tackle from Nick Vlastuin. The controlling umpire called play on, while another umpire down field called a high tackle.

Greene ran around the Tiger on the mark, and booted to goal.

Hardwick was asked about the umpires after the match, and while he didn't want to say too much, the message he was trying to get across was clear.

"Look, I can't really comment on the umpiring, but it would be fair to say we're going to do a bit of ducking practice at training tonight," Hardwick said jokingly.

"The game is incredibly hard to umpire, let's make no mistake about that. It was a pretty good contest, transition-wise it was up and back and it's tough. They get a lot right. Sometimes they get some wrong. That's life.

"The game, as I said, I don't think was dominated by umpiring tonight, I thought we saw a pretty good game of footy that we should be looking at the game and that's how it should be played. Two sides going at it for a long period of time and one side got out the winner."

GWS moved into seventh place following the result, while the Tigers remain in first, but will only remain their on percentage, with either Collingwood or West Coast joining them at the top following their clash on Sunday.
