Really bad news for Moore and the team. If the rumours of a crucial ligament tear are true, then I’m afraid he’s done for this season!
You would usually be looking at around 8 months recovery and rehabilitation time post op.
It’s a horrible injury, probably amongst the worst, not only because of the nature of trauma but also because the rehabilitation usually means months of physiotherapy and gym work spent strengthening the quads and calves etc to build stability around the knee joint.
Hopefully it isn’t a torn ACL and maybe just a medial strain which has a much better prognosis, either way I wish him all the best in his recovery.
