HARRY Kewell is in doubt for Melbourne Heart's clash with champions Central Coast on Saturday after suffering whiplash in the Melbourne derby. But Melbourne Victory is hopeful Mark Milligan will overcome a knee injury and be fit for Friday's visit to Adelaide United. Victory's captain is hoping to manage his knee issue and avoid surgery and club doctors will monitor him closely over the next week. He would miss about five weeks if an arthroscopy was required. Kewell lasted just 68 minutes of the Round 1 derby after feeling the effects of the ball cannoning into him from a Pablo Contreras clearance and Adrian Leijer's accidental forearm, which required stitches. Heart will almost certainly be without Michael Mifsud, who won't return from international duty until late Friday as he's due to play a World Cup qualifier against Denmark on Wednesday. Mifsud celebrated his 100th cap for Malta by scoring although his team lost 4-1 to Czech Republic, while winger Mate Dugandzic has been cleared for Round 2 after succumbing to cramp. "Michael probably won't be available and Harry's pretty sore and sorry at present and we're not ruling him in or out, we'll see how he goes day by day," Heart football operations manager John Didulica said. If he can do some serous training closer to the game he might be a chance but with neck and head injuries it's not an area you want to take risks with. Victory's Archie Thompson and James Troisi have been cleared for Adelaide after coming off with cramp late in the match. Milligan was still sore when he returned to Melbourne on Saturday after the pointless trip to France where his knee flared up after the 24-hour flight, but the diagnosis was better yesterday. "That (surgery) is a last-case scenario but at this stage it can still be managed," Postecoglou said. Prior to the trip he was good, he hadn't missed training and the Adelaide game was the first time he felt it severely but if it was a league game he probably would've kept playing. Going all that way just to come back was disappointing and it didn't do him a great deal of good. He'd gone backwards from the Adelaide game where he got injured but speaking to the medical staff he's probably back to where he was just before he did it so we're hopeful with management he'll be available. Everyone else is good, a couple went down with cramp but that's mainly because they haven't done a massive pre-season and Rashid (Mahazi) got a knee knock. Melbourne Heart coach, John Aloisi, says 'tactically it was a good game' and was happy with how his team executed their game plan.
