i'd prefer to see hayne play but maybe the hammy is worse than they first thought.If he's not 100% fit and there's nothing to gain, why get upset?
Nathan Buckley had hamstring issues when he was playing afl. Kept coming back when it felt ok and kept reinjuring it. Wasn't until after he retired they found out he had a 9cm tear running along the muscle that needed surgery to fix that just wasn't going to repair on its own. Maybe hayne has something similar.
