Dylan Roberton has been hospitalised after briefly collapsing to the ground during the second term of the Geelong/St Kilda clash.
Vision behind the goals showed Roberton collapsing just after the centre bounce.
Roberton was unmanned at the time, with play stopping as a result.
He was eventually helped to his feet and jogged off the field.
"That's a concern," Paul Roos said from the MCG.
St Kilda later confirmed Roberton would be taken to Epworth Hospital for precautionary scans following the collapse.
'Razor' Ray Chamberlain joined Triple M and was asked about his favourite players to umpire. He was quick to name two who were "peerless"!
