14 days in hospital is a really long time. I was in for 12 days and I won't be able to ride for about a year but of course the recovery time is different depending upon injuries. All I know is that noone deserves to go through that so best of luck Aaron, and I hope you'll ride again.
According to his interview with roadracing world (www.roadracingworld.com), he needs 4-6 weeks for his legs and another 2-3 weeks for his shoulder to recover. Full interview is on RRW's (free) website!
