Reds right-back Cameron Watson spoke to the Adelaide Advertiser about the situation, indicating that Cassioâ€™s outburst was just part of the game.
â€œFinals are coming up and everyone wants to do well at training,'' Watson said.
â€œIt happens at training sometimes and it's not the first time it's happened.
â€œYou get tackled and things get a bit fired up but I think it's all part and parcel of sport in general.
â€œI don't think there's anything in it, I wouldn't read too much into it.
â€œI 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.
â€œIt 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.
â€œIt's just competition when you make a mistake players get fired up.
â€œThe best teams in the world have that fire in the belly all the time.''
