No I don't think jaws are like that. You screw them back together, the stitch it up and it mends like other bones in around 6-8 weeks. It's not invasive surgery, i.e. you don't need to cut deep, the face has great blood supply and it's not a load-bearing bone. Pretty sure you can even resume light cardio rapidly after you recover from the surgery.
The biggest issue is contact after healing and you can't wear protection on the jaw.
I'm not a doctor, this is just what I've read about in the past.
But consider that Chris Lawrence returned to footy in 14 weeks after having his face caved in (broken jaw, cracked palate, both cheekbones and both eye sockets broken).
The comp ends in 13 weeks from now for non-finals teams.
