West Coast ruckman Nic Naitanui set for spell on sidelines with groin, back issues Nic Naitanui has been sidelined with groin and back issues. WEST Coast star Nic Naitanui is set to miss several weeks and is no guarantee to play again this season after the Eagles decided he needs a rest. And West Coast coach John Worsfold said Daniel Kerr's knee issues were now threatening his career, despite the veteran onballer being contracted for 2014. Kerr has again suffered swelling in his knee following a hitout for East Fremantle in the WAFL on Saturday. His knee blew up after the game. He's obviously having a tough time of it," Worsfold said. To play AFL footy, you have to be able to play your role. That's just a given. You can't pick players that can't perform at the required level. We know that even at 80 per cent fitness, he can still perform pretty well. But that's getting tougher and tougher with the issues that he's been carrying. Really it's around can we get his body right? I'm sure he's got brilliant football left in him, if he's as sound as he can be. Sandilands shrugs off sickness Worsfold said Naitanui would be rested to help deal with his groin and back issues, with the best-case scenario a return to football in 3-4 weeks. With only six rounds remaining, Naitanui may not be seen again this season if the Eagles drop out of finals contention. "If some of his issues resolve, then we'll build him up and see how he goes," Worsfold said. His back's an ongoing thing. He's just got a back that may flare up at various times throughout his life. The best scenario for us is that Nic's back playing in three or four weeks, which would be wonderful - regardless of our ladder position. Worsfold said Naitanui's groin pain had also flared up over the past month. The All-Australian ruckman had an operation to deal with osteitis pubis last summer. Eagles close to re-signing Woosha Worsfold stopped short of confirming he wanted to coach on for a 13th year in 2014, but spoke expansively about planning for next season in a long press conference at Patersons Stadium. "I'm in the process of giving really serious consideration around my role at the footy club as senior coach and what I can offer the club, what I need to be able to coach this club to the best of my ability," he said. So I'm putting a plan in action to present to the footy club. As much as I'm rapt that the club has indicated that they're very keen for me to coach on, the ultimate decision will be between both of us - to make sure we're both on the exact same page.
