Australia international Tommy Oar will miss the rest of Central Coast Mariners' A-League season with a knee injury.
The midfielder faces a recovery time of up to three months after being hurt in the Gosford club's 1-1 draw with defending premiers Sydney FC at the weekend.
He hyperextended his knee when he landed awkwardly after challenging for a ball in the air, causing a posterior capsule ligament sprain.
The 27-year-old, who has previously had two stints with Brisbane Roar, doesn't need surgery, but will be sidelined for at least ten weeks.
He said: "I am really disappointed to not be able to play again this season. I know I'm in great hands with Dave McGinness and the medical team at the Mariners, so I am putting my full focus into getting myself healthy and fully fit for next season."
Oar, who has played 28 times for the Socceroos, joined Mike Mulvey's side in pre-season on a two-year deal following a spell in Cyprus with APOEL.
His absence is a blow for Central Coast, who are five points adrift of Brisbane at the foot of the A-League table.
Oar's final appearance of the campaign, when they held the Sky Blues away from home, was just the second time in the last seven games they've avoided defeat.
The Mariners have only won one game all season, and will need to pick up a second victory at Central Coast Stadium on Friday against Brisbane if they are to retain hopes of avoiding a second straight wooden spoon.
The Mariners are 7/5 to win their next game against Brisbane Roar, who are 17/10, with the draw 13/5.
