It’s been a bad week for knee injuries with two of the A-League’s bright young attackers suffering long term ACL injuries.

First, Chris Ikonomidis went down with a serious injury and he was followed later in the week by Adelaide United’s Nathan Kostandopoulos.

Perth Glory star Chris Ikonomidis will be forced to miss up to nine to 12 months of football after suffering a devastating knee injury in last weekend’s match against Melbourne Victory.

Scans earlier this week confirmed his worst fears revealing a tear to the left anterior cruciate ligament.

The 24-year-old winger had only been on the pitch for 15 minutes after coming on as a second half sub in last Saturday’s game against Victory, when his strapped left knee buckled after he made what seemed an innocuous pass. Ikonimidis was returning to action after missing Glory’s two previous matches through an injury to the same knee sustained after a heavy Michael Jakobsen tackle in the match against Adelaide United.

The injury is a devastating blow for last year’s A-League Young Player of the Year winner. Ikonomidis was one of the current A-League players in line for Socceroos selection for their World Cup qualifiers this year. He was also a possible selection for the Olyroos’ Olympic games campaign as one of three over-age selections that coach Graham Arnold can include in the team.

The injury is also a blow to Perth Glory as the club strives for A-League and AFC Champions League silverware.

“Obviously we’re all hugely disappointed for Chris,” said Glory Football Director Jacob Burns.

“It’s always difficult when a player suffers a serious injury, but we have an excellent medical team here at the club who will go above and beyond to provide him with all the assistance and support that he needs to make a full recovery.”

“The club will provide regular updates on Chris’ progress via all its media platforms,” said Glory CEO Tony Pignata.

“We look forward to seeing Chris back in action and back to his best sooner rather than later.

Konstandopoulos suffered a knee ligament rupture during midweek training as the Reds prepared for their match against Brisbane Roar this weekend.

Reds Director of Football, Bruce Djite,said “Nathan had scans on his knee yesterday and they have confirmed he has suffered an isolated ACL rupture. With the surgeon’s advice, we will determine what the best next steps are and go from there.”

“This is a devastating blow to Nathan and his teammates; all football staff and the entire Club feels for him during this very challenging time.

“Nathan is a talented footballer and a strong individual with fantastic character, so I know for sure he will come through this challenge and be back better than ever.

“It will be a long and difficult road, but he will have the full support of everyone at Adelaide United throughout his recovery.”
