Reds right-back Cameron Watson spoke to the Adelaide Advertiser about the situation, indicating that Cassio’s outburst was just part of the game.
“Finals are coming up and everyone wants to do well at training,'' Watson said.
“It happens at training sometimes and it's not the first time it's happened.
“You get tackled and things get a bit fired up but I think it's all part and parcel of sport in general.
“I don't think there's anything in it, I wouldn't read too much into it.
“I guess you're not going to have that mentality on the park and you're not going to get results if you're not fired up,'' he added.
“It would be different if people were fighting, but it's just little tackles, little arguments and if you don't have that you're not going to have a good mentality come the weekend.
“It's just competition when you make a mistake players get fired up.
“The best teams in the world have that fire in the belly all the time.''
