Ruck/forward Ryder had surgery on a fractured cheekbone sustained in last weekend's 21-point JLT Community Series win against North Melbourne. Ryder is still a chance for round one, but more likely for the following week. Defender Lienert suffered medial damage to his knee in the same game and could miss up to a month. Key forward Dixon didn't run last week after feeling soreness in his recovery from a broken leg and dislocated ankle. He's likely to miss at least the first month of the season, but could be longer depending on when he can get through a block of training without pain. Vice-captain Hartlett is on track to play in Port's SANFL trial next Friday night in his return from a torn ACL and could be up for AFL selection as early as round two, but round three is more likely. Co-captain Wines will also be due back around the same time. Second-year midfielder Patmore tore his ACL in Port's SANFL trial last Friday night and will miss the rest of the season. - Lee Gaskin
