ST KILDA defender Jake Carlisle has been reported for striking after collecting Richmond forward Jack Riewoldt late in a marking contest during the first quarter in a clash that left the dual Coleman medallist concussed.

Meanwhile, Tigers backman Bachar Houli is expected to miss next week's Dreamtime at the 'G clash with Essendon after suffering a groin injury.

TIGERS WIN TOUGH Full match coverage and stats

Riewoldt held on to a mark five minutes into the match at the MCG on Saturday afternoon but was hit in the head by the Saint's swinging right forearm.

The premiership Tiger stayed down for a while before being helped off the ground with the assistance of trainers and appeared groggy on his feet.

It was confirmed during the second term that Riewoldt's day was over, and during the third that Houli would not return, leaving the Tigers down to two rotations for the second half.

Richmond coach Damien Hardwick didn't know whether Riewoldt would be fit next week when speaking after the game.

"He's fine, he's up and about. How it turns out from here I'm not too sure, we'll go through the correct protocol. Our doctors made a pretty quick decision that he didn't look right, so he was ruled out pretty quickly," Hardwick said.  

The premiership coach wasn't overly concerned about the Carlisle incident. 

"Accidents happen in footy, for mine. It was more that he landed awkwardly that caught everyone off guard, so I don't think there's anything in that," Hardwick said.

Houli left the field in the opening term and went down to the rooms before coming back on to the field.

However, that return didn't last long and he was sent downstairs again.

For the Saints' trip to face West Coast at Optus Stadium next Saturday night, backman Brandon White is in doubt after copping a knock to his right thigh.

"Whitey had a really bad corkie early," St Kilda coach Alan Richardson said.  

"Probably shouldn't have put him back out, not that he was going to do any more harm, but he was just struggling to be able to sprint to defend.

"You know they're pretty slippery in front of the ball, so that was a bit of a challenge, but at that stage we were just starting to get a little bit banged up too and just needed another rotation.

"That's why he went forward, just to soak up a few minutes for us."

Wingman Jack Newnes had a concussion test and onballer Luke Dunstan copped a heavy knock to his right shoulder but both returned to the field and should be right to face the Eagles.
