RICHMOND premiership forward Jack Riewoldt is confident of taking on St Kilda this Saturday, only six days after coughing up blood.  

The dual Coleman medallist had a heavy collision with West Coast's Liam Duggan in the third quarter of the Tigers' 47-point defeat last Sunday.  

Remarkably, Riewoldt played out the match at Optus Stadium to be one of Richmond's best players with five goals.  

Despite there being concerns about the 29-year-old being able to fly back with the team from Perth, Riewoldt says there have been no dramatic after-effects from the incident.  

The two-time All Australian told Fox Footy he wants to take on the Saints at the MCG.  

"It just flushed me in a bit of a bad spot," Riewoldt said about the clash with Duggan.  

"I had a mouthful of blood, spat it out and then went to the bench.  

"The next half an hour I was spitting up a little bit of bloody every now and again. I was never in pain."  

Riewoldt said there was a discussion between club doctor Greg Hickey and flight staff about his well-being, but he was cleared to fly immediately.  

"I was thinking in my seat, 'please I just want to get home'," Riewoldt said.  

The Tigers conceded their spot on top of the ladder to West Coast with the loss.
