Roos calls for 'concussion sub' after Riewoldt clash

Paul Roos has called for the introduction of a ‘concussion sub’ rule after Richmond lost Jack Riewoldt just five minutes into their MCG clash with St Kilda.

Riewoldt, who endured an uncomfortable week after coughing up some blood in last week’s loss to West Coast, was hit by Saints defender Jake Carlisle across the head in a marking contest.

Carlisle was reported for the incident.

Riewoldt fell to the ground and was taken straight down to the rooms.

“This is a problem now,” former Swans premiership coach Roos said in Fox Sports commentary.

“We are not doctors up here but if Riewoldt doesn’t play for the rest of the game this is a significant impediment to the Richmond footy club.

“This is the rule that they need to change. This is the concussion sub. We are in the first five minutes of the game.”

Riewoldt was later ruled out for the remainder of the day, while the Tigers were also without Bachar Houli for a period of the first half with an apparent groin injury.

But Richmond were largely unaffected to the main break and went on to win 15.15 (105) to 12.5 (77).

Damien Hardwick unleashed on the AFL goal review system after a controversial call went against his side.

Jack Higgins was denied a goal when it was determined Tom Hickey had touched the ball before it was completely over the line.

The goal umpire had originally called it a goal, something replay angles from in front of and behind Hickey suggested was correct.
