As indicated in other threads, there have been a couple of statements in the press by Boti and coach Scott indicating that Julius's "tweaked" ankle against the Tigers affected how often he was allowed to train. It has since been reported that as his "tweaked" ankle is now ok, he is back to full trainings.
Having been at the game, and seeing him re-tighten his laces to the max on that foot after he did it, a couple of meters in front of the Melbourne bench no less! I was pretty impressed. He didn't get too many boards if any after that, but he still managed to contribute. His ability to play while injured is impressive. Normal players try to hide an injury and not do that in front of an opponents bench, but an angry Julius is not a normal player.
To my knowledge there has been no press/public statements about Julius sitting out some of the match warm ups. Everyone is just assuming that because it started immediately after his cramping up game it has something to do with that, but no one has confirmed that publicly as far as i know. Would be interesting if someone could find that out.
