HAMILTON Kangaroos captain Kane Uebergang was found guilty of unbecoming conduct at an independent tribunal last night.
Uebergang, 28, was suspended for two matches for a sling tackle on Port Fairy's Sam Martin in round three at Melville Oval.
The strong-bodied leader pleaded not guilty.
Investigations officer Chris Asenjo referred the matter to the tribunal after Port Fairy asked it to be investigated.
Martin played no further part in the May 4 game after the incident in the third term and said he felt "headachy, dizziness, sick and weak".
He did not have any further medical treatment but had symptoms inline with concussion and missed a day of work.
Port Fairy coach Sam Rudolph, who was a witness, ruled Martin out of playing the following week, as is his policy with concussions.
Both clubs used video footage of the match at the tribunal.
It centred on two tackles on the wing the first from a Port Fairy player on a Hamilton opponent, with Uebergang's tackle on Martin following.
Martin, who couldn't remember the incident, said from the footage he believed he grabbed the ball to take advantage of what he believed was a play-on call for a holding-the-ball tackle in the Seagulls' favour.
The free from the first tackle was awarded to the Kangaroos for a sling tackle.
Hamilton Kangaroos advocate Gerard Bourke argued Uebergang's tackle was in play.
Uebergang said he heard the whistle when he was "committed to the tackle".
The Hampden interleague representative said it was a sling tackle but that he felt the force he used was reasonable.
"I was trying to stop him getting an advantage," Uebergang said.
"I tried to grab him around the hips because he had the ball there and to get him to the ground. I thought it was a fair tackle."
Asenjo sent the matter to the tribunal on two points engaging in rough conduct and whether it was out of play.
He said he felt it "falls in the negligent category".
Rudolph and Shaun Murrihy, the Seagulls' second witness, both said they felt Uebergang used unreasonable force in the tackle.
Umpire Tony Bunworth awarded the Kangaroos a free kick for the first tackle and did not see the second tackle take place. But he said both tackles warranted free kicks, not a suspension, after seeing the video at the tribunal hearing.
