Nick Wright reported that it was a full reconstruction, so its hard to say if Nick is just extrapolating or whether more was said.
From memory, Liam's injury was a nerve one, so it could be possible that its a clean up and small repair and not a full reconstruction i.e. the 3-6 month recovery period we're thinking of.
