Terrible for the young bloke. As another poster said, a potential star of the comp. The incidents of serious injuries these days is a worry. It's almost guaranteed every year that several players will cop a season ending injury. Just hope that recent serious injuries to Tomlinson, Lever, vandenBerg et al keep our quota as fulfilled for a while yet.
On another note, there is a lot to be said of the 70's and 80's version of footy training. A couple of laps, kick to kick, circle work maybe a bit of one on one/backs -v-forwards and then a sprint to the sheds for a can of VB! Hell, I even remember blokes having a smoke at half time! BUT....very few serious injuries.
