Brisbane coach Chris Fagan was at a complete loss to explain his team's woeful goalkicking.

Not only was it a 15th straight loss to the Tigers' but almost a carbon-copy of last season's qualifying final defeat where they kicked 8.17. This time it was 4.17.

"We practice and practice and practice and practice and practice, I'll tell you that now," Fagan said. 

"At training we kick quite accurately, and we try and do it when they're fatigued … we follow all the basics of good goalkicking practice.

"It's been an issue for us. We're not avoiding it. 

"I'm not saying it made the difference between winning and losing the game, but it made the difference between the game being a tight game and not a tight game."

Richmond narrowly won the inside 50 count (44-40) and contested possessions (103-97), while Brisbane edged the clearances (28-20), but it was the Tigers' efficiency that won the day. 

"I thought our players showed a lot of grit to keep going because that can be deflating," Fagan said. 

"The effort was there, the intensity was there, the finish wasn't."

Fagan said Cam Rayner would likely miss "two to three" weeks with a hamstring injury that would be scanned on Wednesday.

In better news for Brisbane, Daniel Rich (hamstring), Ryan Lester (hamstring), Grant Birchall (managed) and Dan McStay (suspension) will all be available for Saturday's match against the Western Bulldogs.
