A pre-season hamstring injury has Conca sidelined until mid-way through this season.
Scans revealed he strained his right hamstring in the club’s third-round NAB Challenge match against Port Adelaide.
It marked more tough news for Conca, who also endured a tough 2015 that started with a pre-season hamstring injury.
Once the midfielder worked back, he suffered persistent hamstring injuries, sidelining him for all but two regular season games.
His value was highlighted by the Tigers’ willingness to select him for the elimination final against North Melbourne.
