Brisbane Roar defender Jade North will miss big A-League clash with Central Coast Mariners Brisbane will have to do it without Jade North. ROAR defender Jade North is set to miss Brisbane's A-League clash against Central Coast Mariners in Gosford on Sunday after succumbing to a groin injury. North did not train with his teammates today, with Roar coach Mike Mulvey saying it wasn't worth risking the centre back this weekend. North suffered the injury in the dying stages of Brisbane's 3-0 win over Melbourne Heart last Sunday, joining a casualty list that includes Besart Berisha (hamstring), Shane Stefanutto (hamstring) and Liam Miller (calf). Courier-Mail football writer Marco Monteverde shares his thoughts ahead of round five of the Hyundai A-League this weekend. In the absence of North, James Donachie, yet to taste a minute of A-League action this season, will partner Matt Smith in the centre of Brisbane's defence. "He's just a little bit tight in the groin," Roar coach Mike Mulvey said of North. There's no strain, there's no pull, I'm probably just going to err on the side of caution. It's a long season ahead. We've got every faith in James Donachie. He did really well last season. He's been chomping at the bit, so it'll be his turn to get himself out there and see what he can do. Donachie, 20, started in 17 matches for the Roar last season, several of them in the absence of Smith, whose season was cut short due to hip surgery. "The A-League's about having a decent deep squad and we're quite happy with the quality of our squad," Mulvey said. There's certainly no need to panic with (Donachie) in there. With Henrique expected to start at centre forward role in the ongoing absence of Berisha, and Socceroo Ivan Franjic set to be used in the midfield, the only spot up for grabs is on the right wing. Either Dimitri Petratos, who impressed off the bench last weekend, or Kwame Yeboah will fill the role.
