TIM Mohr's comeback from a stress fracture in his right ankle has hit a major roadblock.
The 25-year-old former Launceston footballer, who was aiming for a senior return about round 5, suffered a medial strain in his left knee at training this week, and will be on the sidelines for a further 4-6 weeks.
The injury is another blow to the Giants' key defensive stocks, with the club to be without co- captain Phil Davis at least in the short-term after suffering a kidney injury in the round 1 clash with Sydney.
Mohr, who has played 35 games for the Giants, is the second former Launceston Football Club player to be injured this week.
Gold Coast midfielder Jesse Lonergan has been sidelined with a fracture in his left hand, sustained in the NEAFL on Saturday.
The injury was still being assessed by the Suns' medical staff yesterday afternoon, with an announcement on how long he will be out of the game expected this afternoon.
