Central Coast Mariners star Marcos Flores has suffered a knee injury at training which could end his A-League season.

The Argentine attacking midfielder will have scans on Friday with fears he has torn the anterior cruciate ligament in his right knee – an injury requiring a knee reconstruction.

“Central Coast Mariners will update Flores’ condition once the scans have been fully analysed by the club’s medical department,” the Mariners said in a statement on Thursday.

Flores signed a one-year contract with the Mariners after the 28-year-old ended stints with Melbourne Victory and Adelaide United, where he won the 2010/11 Johnny Warren medal for the A-League’s best player.

His loss will compound the Mariners’ problems of filling the vacancy of Flores’ attacking midfield partner Michael McGlinchey, who has accepted a loan transfer to Japan’s Vegalta Sendai, coached by former Mariners boss Graham Arnold.
