The outstanding defender is sidelined until the next season after tearing his anterior cruciate ligament in his knee, meaning John Mousinho has lost arguably his outstanding player at the back.
Mousinho has indicated he will now look to the January transfer window for a new recruit in that area to help his side sustain their Championship push.

Highly-touted defender has long had the scouts going to the Pirelli Stadium. Aberdeen and Nottingham Forest some of the more recent names to be linked with the 24-year-old - but perhaps more of a right-back than a central defender. Photo: Joe Dent

Okay, it's nice to dream right! The huge former favourite made his name at Pompey, before making a move to Brighton for around £4m. Has since turned out for Derby and West Brom before being dogged by injury at Middlesbrough. We'll overlook the fact he's left sided and Regan Poole plays on the right, too. Photo: Naomi Baker
