Shane Mumford's manager cries foul over broken cheek Shane Mumford was left with a broken cheek after Sydney's game against Adelaide. SHANE Mumford's manager says AFL rules designed to protect players' heads have failed the Swans ruckman and instead have left him "sucking food through a straw." Mumford was ruled out for a month with a broken cheekbone after a head clash with Adelaide's Jared Petrenko last weekend. Petrenko is expected to miss three weeks with a shoulder injury as a result of the hit. Mumford's manager Anthony McConville was last night fuming that Mumford's injury wasn't raised in the match review panel's review of the Sydney-Adelaide game. "It's disappointing, really disappointing that a player is supposed to be protected from this type of situation yet here we have my client missing four weeks and sucking food through a straw," McConville told The Footy Show. It wasn't even written up in the reports of the match review panel. That is the most disappointing part of all this, that it was just dismissed. Shane is as disappointed as I am. McConville said he believed the decision not to act on the head high contact would have been different if Mumford had injured a smaller player's head. "If the tables had been turned on the weekend and it was Shane doing this to a smaller player then there would have been an outcry," he said. It is understood the match review panel didn't consider Mumford's injury because players aren't charged if a head clash is incidental. Swans midfielder Dan Hannebery said the loss of Mumford was a concern for the side. "The Swans are basically just disappointed he's going to miss four weeks with that injury," Hannebery said. You just want to make sure the player's head is always protected.
